Kinetic Resolution of Racemic α-Arylalkanoic Acids with Achiral Alcohols via the Asymmetric Esterification Using Carboxylic Anhydrides and Acyl-Transfer Catalysts
TL;DR: This protocol was successfully applied to the production of nonracemic nonsteroidal anti-inflammatory drugs from racemic compounds utilizing the transacylation process to generate the mixed anHydrides from the acid components with the suitable carboxylic anhydrides.
Journal ArticleDOI
Kinetic resolution of the racemic 2-hydroxyalkanoates using the enantioselective mixed-anhydride method with pivalic anhydride and a chiral acyl-transfer catalyst.
TL;DR: This protocol directly provides the desired chiral 2-hydroxyalkanoate derivatives from achiral diarylacetic acid and racemic secondary alcohols that do not include the sec-phenethyl alcohol moiety by using the transacylation process to generate the mixed anHydrides from the acid components with bulky carboxylic anhydrides under the influence of the chiral acyl-transfer catalyst.
Journal ArticleDOI
The first asymmetric esterification of free carboxylic acids with racemic alcohols using benzoic anhydrides and tetramisole derivatives: an application to the kinetic resolution of secondary benzylic alcohols

TL;DR: In this article, a variety of optically active carboxylic esters are produced by the kinetic resolution of racemic secondary benzylic alcohols using free carboxyl acids with benzoic anhydride and tetramisole derivatives.
Journal ArticleDOI
Kinetic Resolution of Racemic Carboxylic Acids Using Achiral Alcohols by the Promotion of Benzoic Anhydrides and Tetramisole Derivatives: Production of Chiral Nonsteroidal Anti-Inflammatory Drugs and Their Esters
TL;DR: In this article, a variety of optically active carboxylic esters were produced by kinetic resolution of racemic carboxyl acids by using achiral alcohols, benzoic anhydrides, and Birman's tetramisole-type catalysts.
Journal ArticleDOI
Asymmetric Epoxidation with a Photoactivated [Ru(salen)] Complex
TL;DR: (Nitrosyl)(salen)ruthenium(II) complex 1 was found to serve as an efficient catalyst for the epoxidation of conjugated olefins under photoirradiation, with 2,6-dichloropyridine N-oxide (2) or tetramethylpyrazine N,N'-dioxide as a stoichiometric oxidant.
