Synthesis of (4Z)-4-(Arylmethylidene)-5-ethoxy-1,3-oxazolidine-2-thiones by the Reaction of Ethyl (2Z)-3-Aryl-2-isothiocyanatoprop-2-enoates with Organolithium Compounds

A convenient one-pot method for the preparation of (4Z)-4-(arylmethylidene)-5-ethoxy-1,3-oxazolidine-2-thiones 2 and 3 from ethyl (2Z)-3-aryl-2-isothiocyanatoprop-2-enoates 1, which can be easily prepared from ethyl 2-azidoacetate and aromatic aldehydes, has been developed. Thus, these -isothiocyanato ,-unsaturated esters were treated with organolithium compounds, including lithium enolates of acetates, to provide 5-substituted (4Z)-4-(arylmethylidene)-5-ethoxy-1,3-oxazolidine-2-thiones, 2, and 2-[(4Z)-(4-arylmethylidene)-5-ethoxy-2-thioxo-1,3-oxazolidin-5-yl]acetates, 3.

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.

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 90319-52-1, in my other articles.

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.

Real-Time Synchrotron Small-Angle X-ray Scattering Studies of Collagen Structure during Leather Processing

The collagen structure in skins is significantly influenced by the cross-linking chemistry adopted during leather processing. We have developed an in situ technique to measure real-time collagen structure changes using synchrotron-based small-angle X-ray scattering (SAXS). Three common mineral tanning systems, basic chromium sulfate (BCS), zirconium sulfate (ZIR) and an aluminosilicate-based reagent (ALS) were used to stabilize collagen in ovine skin. Studying the molecular changes by in situ SAXS revealed a range of tanning mechanisms: a complex combination of covalent cross-linking, electrostatic interactions and hydrogen bonding by BCS, hydrogen bonding interactions by ZIR, and the formation of colloidal aggregates by ALS. These results unravel the mechanisms of producing leathers with different properties, explaining why ZIR produces denser leathers while ALS produces softer leathers compared to conventional BCS leathers. ZIR and ALS are environment-friendly alternatives to BCS, and understanding their mechanisms is important for a more sustainable future for the leather industry.

Benzoxazoles as novel herbicidal agents

BACKGROUND Despite the need to develop new herbicides with different modes of action, due to weed resistance, many important classes of compounds have been studied poorly for this purpose. Benzoxazoles are considered privileged structures because of their biological activities, but their phytotoxic activities have not received a lot of attention until now. RESULTS CONCLUSION Scheme Double vinylic substitution reactions were carried out to furnish four 2-nitromethylbenzoxazoles and one oxazolidine. Benzoxazol-2-ylmethanamine was obtained by reduction of compound 3a. These compounds were evaluated for their phytotoxicity in Allium cepa (onion), Solanum lycopersicum (tomato), Cucumis sativus (cucumber) and Sorghum bicolor (sorghum). Comparison with oxazolidine analogue allowed us to understand that the benzoxazolic structure is very important for the herbicidal activity. All the synthesized compounds exhibited biological activity on seed germination. The four 2-nitromethylbenzoxazoles showed phytotoxic activity and the 5-chloro-2-(nitromethyl)benzo[d]oxazole (3b) exhibited higher inhibition than the commercial herbicide against all four plant species tested.

Mefloquine-Oxazolidine Derivatives: A New Class of Anticancer Agents

A series of 23 racemic mefloquine-oxazolidine derivatives, 4-[3-(aryl)hexahydro[1,3]oxazolo[3,4-a]pyridin-1-yl]-2,8-bis(trifluoromethyl)quinolines, derived from (R*, S*)-(+/-)-mefloquine and arenealdehydes, have been evaluated for their activity against four cancer cell lines (HCT-8, OVCAR-8, HL-60, and SF-295). Good cytotoxicities have been determined with IC50 values ranging from 0.59 to 4.79g/mL. In general compounds with aryl groups having strong electron-releasing substituents, such as HO and MeO, or electron-rich heteroaryl groups, for example imidazol-2-y-l, are active. However, other factors such as steric effects may play a role. As both the active and non-active conformations of the mefloquine-oxazolidine derivatives are similar, it is concluded that molecular conformations do not play a significant role either. This study is the first to evaluate mefloquine derivatives as antitumor agents. The mefloquine-oxazolidine derivatives are considered to be useful leads for the rational design of new antitumor agents.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 90319-52-1. SDS of cas: 90319-52-1.

1D-Coordination Polymer Formed by Structural Conversion of an Oxazolidine Ligand in Reaction with the Copper(II) Halides

A 1D-coordination polymer of 1D-{Cu(mu-picolinato)(2)} {Hakimi, 2012 #73}(n) (1), was prepared by the reactions between 2-(2-(pyridin-2-yl)oxazolidin-3-yl)ethanol (AEPC) ligand and CuCl2 or CuBr2. The product was characterized by elemental analysis, UV-Vis, FT-IR spectroscopy and single-crystal X-ray diffraction. The X-ray analysis results revealed that the AEPC ligand, after reactions with the copper(II) chloride or bromide, gives the same product – 1D- {Cu(mu-picolinato)(2)}(n) (1). The coordination modes for various picolinate-based ligands were extracted from the Cambridge Structural Database (CSD). In the crystal structure of 1, the copper atom has a CuN2O4 environment and octahedral geometry, which is distorted by elongation of the axial bond lengths due to the Jahn-Teller effect.

Synthesis and diuretic activities of pseudoproline-containing analogues of the insect kinin core pentapeptide

C-2 dimethylated/unmethylated thiazolidine-4-carboxylic acid and C-2 dimethylated oxazolidine-4-carboxylic acid were introduced into the insect kinin core pentapeptide in place of Pro(3), yielding three new analogues. NMR analysis revealed that the peptide bond of Phe(2)-pseudoproline (Psi Pro)(3) is practically 100% in cis conformation in the case of dimethylated pseudoproline-containing analogues, about 50% cis for the thiazolidine-4-carboxylic acid analogue and about 33% cis for the parent Pro(3) peptide. The diuretic activities are consistent with the population of cis conformation of the Phe(2)-Psi Pro(3)/Pro(3) peptide bonds, and the results confirm a cis Phe-Pro bond as bioactive conformation.
