Sequential Kinetic Resolution of (+/-)-2,3-Butanediol in Organic Solvent Using Lipase From Pseudomonas cepacia.

Lipase from Pseudomonas capacia (PCL, Amano PS) catalyzed the enantioselective diacetylation of (+/-)-2,3-butanediol in vinyl acetate.Both acetylation steps favored the (R)-enantiomer (E1 = 12, E2 = 34), thus the reaction is a sequential kinetic resolution.The enantioselectivities of the two steps reinforced one another because both steps proceeded at comparable rates (S = 3) yielding an overall enantioselectivity of approximately 200.A synthetic-scale resolution starting from 2.7 g of (+/-)-2,3-butanediol yielded the diacetate ester of (R)-(-)-butanediol with 96percent ee (1.6 g, 30percent yield) and (S)-(+)-butanediol with 99percent ee (0.63 g, 23percentyield).This preparation is carried out entirely in organic solvent, thereby avoiding the difficult and low yield extraction of 2,3-butanediol from aqueous solution.

Adrenaline profiling of lipases and esterases with 1,2-diol and carbohydrate acetates

The adrenaline test for enzymes is a general back-titration procedure to detect 1,2-diols, 1,2-aminoalcohols and α-hydroxyketones reaction products of enzyme catalysis by colorimetry. The method was used to profile a series of esterases and lipases for their esterolytic activity on a series of carbohydrate and polyol acetates. Substrates were prepared by peracetylation and used for parallel microtiter-plate analysis of enzyme activities. This method can be used to achieve a rapid and automated characterization of a set of enzymes during HTS screening.
