1-Methoxy-3-trimethylsiloxy-1,3-butadiene (Danishefsky-s diene) is recognized as a synthetically useful diene due to its high reactivity in the Diels-Alder reaction with electron-deficient alkenes to give oxygen-functionalyzed cyclohexenes and substituted cyclohexenones, which are important building blocks for the total synthesis of natural products. However, the development of catalytic enantioselective versions of Diels-Alder reactions using Danishefsky type dienes with electron-deficient alkenes has been difficult because of the instability of the dienes under Lewis acidic conditions. Only highly reactive C=O and C=N double bonds are employed in a hetero-Diels-Alder reaction which proceeds under catalysis of chiral Lewis acids. We have developed a new chiral ligand, BINAMIDE, which is easily prepared from 1,1?-binaphtyl-2,2?-diamine by acylation. The highly diastereo- and enantioselective Diels-Alder reaction of Danishefsky type dienes with electron-deficient alkenes in the presence of an Yb(III)-BINAMIDE complex has been developed. The reaction proceeded in an exoselective mode and gave chiral highly functionalized cyclohexene derivatives in good yields. Copyright

An efficient, broadly applicable, operationally simple, and divergent process for the transformation of imides into a range of carboxylic acid derivatives under mild conditions is reported. By simply using catalytic amounts of ytterbium(III) triflate as a Lewis acid promoter in the presence of alcohols, water, amines, or N,O-dimethylhydroxylamine, a broad range of imides is smoothly and readily converted to the corresponding esters, carboxylic acids, amides, and Weinreb amides in good yields. This method notably enables an easy cleavage of oxazolidinone-based auxiliaries.

In this study the modulation of the pharmacological profile from agonist to antagonist was successfully obtained by replacing the methyl group in position 6 of the 1,4-dioxane scaffold of the potent M2/M3 muscarinic agonist 1 with bulkier groups. In particular, the 6,6-diphenyl substitution provided the potent M3 preferring antagonist (±)-17, which in in vivo study proved to be effective in reducing the volume-induced contractions of rat urinary bladder and was devoid of cardiovascular effects.

(Chemical Equation Presented) Rhodium-catalyzed carbozincation of ynamides using diorganozinc reagents or functionalized organozinc halides is described.Using a tri(2-furyl)phosphine-modified rhodium catalyst, the reaction course is altered to hydrozincation when diethylzinc is employed as the organozinc reagent. Trapping of the alkenylzinc intermediates produced in these reactions in further functionalization reactions is possible. Collectively, these processes enable access to a range of multisubstituted enamides in stereo- and regiocontrolled fashion.

[Chemical Equation Presented] Pamamycin 621A was synthesized through a convergent route, with the THF rings constructed from Evans aldols in the presence of the chiral auxiliaries without suffering racemization or elimination. The basic amino group was introduced at a late stage through reduction of an azido group with n-Bu3SnH, which also demonstrates for the first time the great potential of this largely forgotten reduction protocol in synthesis of multifunctional substrates.

Binary room-temperature complex electrolytes have been synthesized based on lithium perchlorate (LiClO4) and organic molecules with acylamino groups, including acetamide, ethyleneurea, 2-oxazolidinone (OZO), urea, methylurea (NMU) and 1,3-dimethylurea (DMU). Both LiClO4 and all organic molecules with acylamino groups are solid at room-temperature, but their mixtures at the proper molar ratio are liquid with a liquidus temperature about below 25C characterized by differential scanning calorimetry (DSC). Infrared spectroscopic studies show that the organic molecules can coordinate with the Li+ cation and the ClO4- anion via their polar groups (the C=O and NH groups). Such strong interactions lead to the dissociation of LiClO4 and the breakage of the hydrogen bonds among the organic molecules, resulting in the formation of the complex systems. Electrochemical performances of the complex electrolytes are evaluated with ac impedance spectroscopy, cyclic voltammetry (CV), and in a test electric double layer capacitor (EDLC), respectively. The LiClO4-acetamide electrolyte at molar ratio 1:5.5 exhibits the highest ionic conductivity, 1.25×10-3 Scm-1 at 25C and 11.5×10 -3 Scm-1 at 80C. The analysis for the CV behavior indicates that the electrochemical stability windowof these electrolytes is above 3V. The results demonstrate that these complex systems are promising electrolyte candidates for supercapacitor and probably other electrochemical devices.

A new amphiphilic biodegradable beta-cyclodextrin/poly(l-leucine) (beta-CD-PLLA) copolymer was synthesized by ring-opening polymerization of N-carboxy-l-alanine anhydride (LL-NCA) in N,N-dimethylformamide (DMF) initiated by mono-6-amino-beta-cyclodextrin (H2N-beta-CD). The structures of the copolymers were determined by IR, 1H NMR and GPC. The fluorescence technique was used to determine the critical micelle concentrations (CMC) of copolymer micelle solution. The diameter and distribution of micelles were characterized by dynamic light scattering (DLS) and its shape was observed by transmission electron microscopy (TEM). The results showed that LL-NCA could be initiated by H2N-beta-CD to produce the copolymer. These copolymers could self-assemble into nano-micelles in water. The CMC of copolymer solution and the size of micelle reduced with increasing proportion of the hydrophobic part. TEM images demonstrated the micelles are all spherical. Such block copolymers could be expected to find applications in drug delivery systems and other biomedical fields.

1H NMR spectroscopic methods have been applied to compare the in vitro reactivity of the renal papillary nephrotoxin 2-bromoethanamine (BEA) with those of selected halide-substituted nephrotoxic analogues, 2-chloroethanamine (CEA), 2-fluoroethanamine (FEA), and 1-phenyl-2-iodoethanamine (PIEA). The primary 1H NMR-detectable transformation during a 24 h incubation of confluent Madin Darby canine kidney (MDCK) cells with BEA, CEA, and FEA (at concentrations up to the IC50 determined by neutral red uptake) was the appearance in cell culture media of 2-oxazolidone (OX). Additional novel signals assigned as FEA carbamate (N-carbanoyl-2-fluoroethanamine) were observed in media collected following incubation of cells with FEA. We propose that N-carbamate intermediates are formed from the spontaneous reaction of these haloalkylamines with HCO3–buffered growth media and that OX is formed from the carbamate via elimination of the hydrogen halide. Further 1H NMR experiments, conducted for up to 8 h at 25 deg C on 5 mM solutions of BEA, CEA, and FEA in (2)H2O containing a 20-fold excess of HCO3- at pH 7.6, demonstrated a time-dependent decrease in the concentration of the free haloalkylamines accompanied by the production of N-carbamate intermediates and OX. Under these pseudo-first-order reaction conditions, the formation of OX from BEA was complete within approximately 6 h. In similar reaction conditions OX formation from CEA (24 h after initiation) had reached 54 percent of its final equilibrium concentration. Equivalent experiments demonstrated that PIEA was almost completely converted to 4-phenyl-2-oxazolidinone (PHOX) within 2 h. These observations reveal the strong disposition of this series of haloalkylamines toward reaction with HCO3- and indicate that the compounds in this family may exist only transiently as free amines in vivo, where there will virtually always be excess HCO3-. The physiological relevance of the in vitro findings is further indicated by the NMR-detectable conversion of BEA to OX and also an alkylating aziridine (AZ) moiety in rat plasma containing BEA. The ability to form carbamoylated species and OX (or PHOX) may mediate the toxicity of this series of haloalkylamines and hence is potentially of considerable significance.

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.Quality Control of Oxazolidin-2-one, you can also check out more blogs about497-25-6
