Pig Liver Esterase Catalyzed Hydrolyses of Racemic α-Substituted α-Hydroxy Esters

Pig liver esterase catalyzed hydrolyses of some α-substituted α-hydroxy esters give product acids and recovered esters in 9-94percent enantiomeric excess.The observed enantiomeric selectivity could be rationalized using a recently proposed active site mod

SYNTHESE D'α-HYDROXYACIDES OPTIQUEMENT ACTIFS PAR ADDITION D'ORGANOZINCIQUES SUR LE PHENYLGLYOXALATE DE (-) MENTHYLE

Organozinc compounds readily obtained in situ from Grignard reagents and solutions of ZnCl2 or ZnBr2 in diethylether or THF add selectively to the keto group of (-) menthyl phenylglyoxalate.A variety of α-substituted mandelic acids o

SYNTHESIS OF ENANTIOMERICALLY ENRICHED ATROLACTIC ACID AND OTHER α-HYDROXY ACIDS

The α-anions of 2-substituted 1,3-dioxolan-4-ones derived from chiral mandelic and lattic acid (2a, 2b; 3a; 10a, 10b) were alkylated with high stereoselectivity, The products formed were hydrolysed to α-hydroxy acids with 65-85percent e.e. ((S)(+)-5,7,9, (R)(-)-13).
