Crystal structures, Hirshfeld surface analysis and PIXEL energy calculations of three trifluoromethylquinoline derivatives: further analyses of fluorine close contacts in trifluoromethylated derivatives

As many studies have revealed, the introduction of a CF3 group into an organic compound can result in significant enhancement of biological activity. Factors which lead to this enhancement are thus of great interest. To investigate further this area, we have looked at the ability of fluorine to form close contacts with various atoms in organic compounds, e.g. F center dot center dot center dot F, F center dot center dot center dot O/O center dot center dot center dot F, F center dot center dot center dot C/C center dot center dot center dot F, H center dot center dot center dot F/F center dot center dot center dot H and F center dot center dot center dot N/N center dot center dot center dot F, as indicated from crystal structure determinations and Hirshfeld analysis studies on trifluoromethylated compounds. Herein we first report the crystal structures, Hirshfeld surface analyses (HSA), and PIXEL energy calculations of three trifluoromethylated quinoline derivatives, namely 2-(trifluoromethyl) quinolin-4-ol, 1, 4-ethoxy-2-(trifluoromethyl)quinoline, 2, and N-1-(2,8-bis(trifluoromethyl)quinolin-4-yl)ethane-1,2-diamine, 3. Of particular interest is the determination of the various fluorine. atom close contacts. The total percentages of fluorine. -atom close contacts in compounds 1-3 were determined to be high at 47, 41.2 and 60.7%, respectively. As relatively few HSA studies on trifluoromethylated compounds have reported the percentages of individual atom atom close contacts, we have also determined the percentages of atom center dot center dot center dot atom close contacts for 20 more trifluoromethylated compounds: the range of total fluorine center dot center dot center dot atom close contacts for these compounds was 20-60%. While these data are based on connections between similar molecules in a crystalline state, they also clearly suggest that a compound containing CF3 group(s) has the potential to make extensive intermolecular connections/close contacts with organic material. Thus a possible factor for the enhanced biological activity of a compound bearing CF3 group(s) could be the propensity of the CF3 group to form many close contacts, thereby aiding binding or interaction with a biological target.

Formation of Heterocyclic and Polycyclic Compounds from Amino Alcohols and Dialdehydes

Amino alcohols typically react with aldehydes to produce oxazolidines. It was hypothesized that the condensation of several commercially available amino alcohols with dialdehydes would produce a series of bicyclic oxazolidines containing two secondary amines. However, there were remarkable differences in the type of products formed depending on the structure of the dicarbonyl compounds and the reaction conditions. When linear aliphatic dialdehydes such as glyoxal were used, the expected bis-oxazolidines were not produced; instead, polycyclic structures or oxazines were formed. However, when cyclic dialdehydes such as 1,3/1,4 cyclohexane dicarboxaldehyde were used, they resulted in products bearing the desired oxazolidine moieties.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 99395-88-7, in my other articles.

Enantiopure alpha-Trifluoromethylated Aziridine-2-carboxylic Acid (alpha-TfmAzy): Synthesis and Peptide Coupling

A straightforward synthesis of enantiopure alpha-trifluoromethyl aziridine-2-carboxylic acid (alpha-TfmAzy) is reported from a trifluoropyruvate derived enantiopure oxazolidine. A key Strecker-type synthetic step and a late cyanide basic hydrolysis gave the target compounds in six steps and 41% yield. A final peptide coupling was performed to demonstrate the usefulness of this highly constrained fluorinated unnatural amino acid.

Exploring the crystallization landscape of cadmium bis(N-hydroxyethyl, N-isopropyldithiocarbamate), Cd[S2CN(iPr)CH2CH2OH](2)

Crystallization of Cd[S2CN(iPr)CH2CH2OH](2) from ethanol yields the coordination polymer [{Cd[S2CN(iPr) CH2CH2OH](2)}center dot EtOH](infinity) (1) within 3 h. When the solution is allowed to stand for another hour, the needles begin to dissolve and prisms emerge of the supramolecular isomer (SI), binuclear {Cd[S2CN(iPr)CH2CH2OH](2)}(2)center dot 2EtOH(2). These have been fully characterized spectroscopically and by X-ray crystallography. Polymeric 1 has 2-fold symmetry and features dithiocarbamate ligands coordinating two octahedral Cd atoms in a mu(2)kappa(2)-tridentate mode. Binuclear 2 is centrosymmetric with two ligands being mu(2)kappa(2)-tridentate as for 1 but the other two being kappa(2)-chelating leading to square pyramidal geometries. The conversion of the kinetic crystallization product, 1, to thermodynamic 2 is irreversible but transformations mediated by recrystallization (ethanol and acetonitrile) to related literature SI species, namely coordination polymer [{Cd[S2CN(iPr)CH2CH2OH](2)}(3)center dot MeCN](8) and binuclear {Cd[S2CN(iPr)CH2-CH2OH](2)}(2)center dot 2H2O center dot 2MeCN, are demonstrated, some of which are reversible. Three other crystallization outcomes are described whereby crystal structures were obtained for the 1:2 co-crystal {Cd[S2CN(iPr)CH2CH2OH](2)}(2) :2[3-(propan-2-yl)-1,3-oxazolidine-2-thione] (3), the salt co-crystal [iPr NH2(CH2CH2OH)](4)[SO4](2){Cd[S2CN(iPr)CH2CH2OH](2)}(2) (4) and the salt [iPrNH(2)(CH2CH2OH)]{Cd[S2CN(iPr)CH2CH2OH](3)} (5). These arise as a result of decomposition/oxidation of the dithiocarbamate ligands. In each of 3 and 4 the binuclear {Cd[S2CN(iPr)CH2CH2OH](2)}(2) SI, as in 2, is observed strongly suggesting a thermodynamic preference for this form.

(R)-2-Phenoxy-1-(4-phenyl-2-sulfanylidene-1,3-oxazolidin-3-yl)ethanone

The central 1,3-oxazolidine-2-thione ring in the title compound, C17H15NO3S, is approximately planar with maximum deviations of 0.036 (4) and -0.041 (5) angstrom for the O and methylene-C atoms, respectively. The dihedral angles formed between this plane and the two benzene rings, which lie to the same side of the central plane, are 86.5 (2) [ring-bound benzene] and 50.6 (3)degrees. The ethan-1-one residue is also twisted out of the central plane, forming a O-C-N-C torsion angle of 151.5 (5)degrees. The dihedral angle formed by the benzene rings is 62.8 (2)degrees so that overall, the molecule has a twisted U-shape. In the crystal, molecules are linked into supramolecular arrays two molecules thick in the bc plane through C-H center dot center dot center dot O, C-H center dot center dot center dot S and C-H center dot center dot center dot pi interactions.

Convergent and enantioselective syntheses of cytosolic phospholipase A(2)alpha inhibiting N-(1-indazol-1-ylpropan-2-yl) carbamates

Cytosolic phospholipase A(2)alpha (cPLA(2)alpha) is an important enzyme of the inflammation cascade. Therefore, inhibitors of cPLA(2)alpha are assumed to be promising drug candidates for the treatment of inflammatory disorders. Recently we have found that indole-5-carboxylic acid with a 3-(4-octylphenoxy)-2-(phenoxycarbonylamino) propyl substituent in position 1 is an inhibitor of cPLA(2)alpha. We have now synthesized a corresponding derivative with the indole heterocycle replaced by an indazole (4) employing an analogous reaction sequence as for the synthesis of the indole derivative. Besides, a more convergent synthesis for 4 was established using an aziridine as central intermediate. Furthermore, a chiral-pool based enantioselective synthesis was developed for the synthesis of (R)- and (S)-4. Starting compound for both enantiomers was the (R)-serine derived oxazolidine (R)-25. Compound 4 proved to be a moderate inhibitor of cPLA(2)alpha, with the S-enantiomer being twice as active as the R-enantiomer. The racemate 4 and the enantiomers (R)-and (S)-4 showed a high in vitro metabolic stability in rat liver S9 fractions.

Synthesis of 3-Fluoro-2-hetarylindoles and 3,3-Difluoro-2-hetarylindolines through Lewis Acid-Catalyzed Formation of 3,3-Difluoroindolium Ions

Synthesis of 3-fluoro-2-hetarylindoles through addition of hetarenes to 3,3-difluoroindolium ions generated in situ by Zn(OTf)(2)-catalyzed oxazolidine ring opening is described. Indoles, pyrroles and alkyl-substituted furans can be used as hetaryl nucleophiles to afford a range of 3-fluoro-2-hetarylindole products 6 in 56-95% yields. A diverse array of 3,3-difluorinated 2-hetarylindolines 7 can also be synthesized in 43-84% yields by a tandem sequential process that involves hetarene nucleophilic addition, HF elimination and fluorocyclization reactions. Our study by H-1 NMR and UV/Vis spectroscopy reveals that 3,3-difluorinated 2-hetarylindolines possess interesting substituent-dependent acidochromic properties. UV absorption and fluorescence spectra of selected compounds 6 and 7 are also studied.

Synthesis and Application of 1,2-Aminoalcohols with Neoisopulegol-Based Octahydrobenzofuran Core

A library of 1,2-aminoalcohol derivatives with a neoisopulegol-based octahydrobenzofuran core was developed and applied as chiral catalysts in the addition of diethylzinc to benzaldehyde. The allylic chlorination of (+)-neoisopulegol, derived from natural (-)-isopulegol followed by cyclization, gave the key methyleneoctahydrobenzofuran intermediate. The stereoselective epoxidation of the key intermediate and subsequent oxirane ring opening with primary amines afforded the required 1,2-aminoalcohols. The ring closure of the secondary amine analogues with formaldehyde provided spiro-oxazolidine ring systems. The dihydroxylation of the methylenetetrahydrofuran moiety with OsO4/NMO (4-methylmorpholine N-oxide) resulted in the formation of a neoisopulegol-based diol in a highly stereoselective reaction. The antimicrobial activity of both the aminoalcohol derivatives and the diol was also explored.

Huge Electro-/Photo-/Acidoinduced Second-Order Nonlinear Contrasts From Multiaddressable Indolinooxazolodine

In this work, linear and nonlinear optical properties of electro-/acido-/photoswitchable indolino[2,1-b]oxazolidine derivatives were investigated. The linear optical properties of the closed and open forms have been characterized by UV-visible and IR spectroscopies associated with DFT calculations. Nonlinear optical properties of the compounds have been obtained by ex situ and in situ hyper-Rayleigh experiments in solution. We show that protonated, oxidized, and irradiated open forms exhibit the same visible absorption and NLO features. In particular, the closed and open forms exhibit a huge contrast of the first hyperpolarizability with an enhancement factor of 40-45. Additionally, we have designed an original electrochemical cell that allows to monitor in situ the hyper-Rayleigh response upon electrical stimulus. We report notably a partial but good and reversible NLO contrast in situ during oxidation/reduction cycles. Thereby, indolinooxazolidine moieties are versatile trimodal switchable units which are very promising for applications in devices.
