- Aminolysis of carboxylic acid esters in direct, bicontinual, and inverse microemulsions based on cetyltrimethylammonium bromide
-
The reactivity of primary alkylamines in cleavage of p-nitrophenyl esters of carboxylic acids in microemulsions of different structures based on cetyltrimethylammonium bromide was studied. The aminolysis rate considerably increases in going from inverse to direct microemulsions, mainly owing to the concentration of the reactants in the boundary layer. 2005 Pleiades Publishing, Inc.

- Coprecipitation of Pseudomonas fluorescens lipase with hydrophobic compounds as an approach to its immobilization for catalysis in nonaqueous media
-
The precipitation of N-cetylamine, N-cetylacetamide, hexadecane-1,2-diol, cetyl alcohol, and poly(butyl metacrylate) in acetone-water media in the presence of the lipase from Pseudomonas fluorescens was found to be accompanied by the coprecipitation of th

- Environmentally benign decarboxylative: N-, O-, and S-Acetylations and acylations
-
An operationally simple and general method for acetylation and acylation of a wide variety of substrates (amines, alcohols, phenols, thiols, and hydrazones) has been reported. Meldrum's acid and its derivatives have been used as an air-stable, non-volatile, cost-effective, and easy to handle acetylating/acylating agent. Easily separable byproducts (CO2 and acetone) allowed the isolation of analytically pure acetylated products without the requirement of work-up and any chromatography. This journal is

- Bis(dialkylaminethiocarbonyl)disulfides as potent and selective monoglyceride lipase inhibitors
-
Monoglyceride lipase (MGL) inhibition may offer an approach in treating diseases in which higher 2-arachidonoyglycerol activity would be beneficial. We report here the synthesis and pharmacological evaluation of bis(dialkylaminethiocarbonyl)disulfide derivatives as irreversible MGL inhibitors. Inhibition occurs through interactions with MGL C208 and C242 residues, and these derivatives exhibit high inhibition selectivity over fatty acid amide hydrolase, another endocannabinoid-hydrolyzing enzyme. 2009 American Chemical Society.

- Nucleophilic substitution in carboxylic esters in oil-in-water microemulsions
-
In hydrolysis and aminolysis of p-nitrophenyl esters of carboxylic acids in oil-in-water microemulsions on the basis of surfactants of various nature, a complex mechanism of the effect of the medium is operative, including shift of acid-base equilibria in the nucleophile. The rate constants of the processes studied are quantitatively related to the surface potential of the microdroplet. Varied hydrophobicity of the nucleophile and substrate changes the site of the reaction act and the relative contributions of aminolysis and hydrolysis.

- A novel one-pot method for reductive conversion of azides to acyl amines with acetic anhydride and trimethyl chlorosilane

A combination of acetic anhydride and chloro-trimethylsilane has been shown to effect the conversion of a variety of azides to the corresponding acetylated amines in excellent yields without affecting other functional groups such as ether, ester, halide etc.
