Racemic methyl 2-(2,4-dichlorophenoxy)propionate (±)-1, was subjected to hydrolysis in water and in a series of two-phase aqueous organic media in the presence of Candida rugosa lipase (CRL). The biocatalytic material used was the commercial preparation and enzyme purified by using different procedures. The (+)-R- and (−)-S-2-(2,4-dichlorophenoxy)propionic acids (3) were obtained in excellent yield

A versatile and sustainable approach to one of the most commonly employed families of herbicides has been developed, which is based on a biocatalytic reductive dehalogenation followed by simple chemical manipulations. A range of commercially relevant target molecules have been obtained in good yield and moderate to excellent enantioselectivity (to either enantiomer), without chromatographic purifications

enantiomerically pure (R)-(+)-DCPP and (S)-(-)-DCPP. The observed inhibition pattern was that of partial noncompetitive inhibition for (R)-(+)-DCPP and that of pure noncompetitive inhibition for (S)-(-)-DCPP. Enantioselective biocatalysis in aqueous' and nonaqueousZ media is becoming increasingly important as a possible alternative method for the resolution of enantiomers. In recent years, hydrolytic enzymes such
