A new catalytic enantioselective synthesis of monosubstituted oxiranes has been developed from achiral trichloromethyl ketones by (a) enantioselective carbonyl reduction, (b) selective bis-dechlorination and (c) base-induced ring closure of the resulting chlorohydrins.

Chiral trichloromethyl carbinols 3, readily available by catalytic enantioselective reduction of trichloromethyl ketones, are converted with inversion of configuration into chiral α-aryloxy and α-hydroxy carboxylic acid derivatives.
