An efficient enzymatic resolution of 7,7-disubstituted 1,4,5,6-tetrachlorobicyclohept-5-en-2-ols was accomplished by means of lipase AY-30 from Candida cylindracea in toluene.When acid anhydrides were used as acyl donors, the enantioselectivity was found to depend strongly on the reaction conditions: Whereas low selectivity (E 200).Alternatively, adsorption of the biocatalyst onto Celite was equally effective (E >300).Complete specificity was obtained when vinyl acetate was used as acyl donor (E ca.1000).
