phenylthiazole-based amines by enantiomer-selective acylation of racemic amines and by hydrolysis of the corresponding racemic amides using lipase B from Candida antarctica (Novozyme 435) as chiral catalyst was performed with good yields and excellent enantioselectivities. In order to prevent the frequently occurring partial racemization of enantiopure amides during chemical hydrolysis to the corresponding (R)-amines
