ABSTRACT:
Biotechnological resolution by means of enzymatic transesterification of the relevant racemic mixture of the optical isomers of .alpha.-alkyl-substituted primary alcohols having the formula (I): ##STR1## wherein: R represents a linear or branched (C.sub.1 -C.sub.20)-alkyl or alkenyl group or an aryl group, also substituted or condensed with other groups, in particular a group of formula (II) or (III): ##STR2## wherein: R.sup.ii represents a (C.sub.1 -C.sub.8)-alkyl group, a (C.sub.1 -C.sub.4)-alkenyl group, an alkoxy, phenyl, phenoxy, benzoyl, or heterocyclic group;
