Abstract
A series of regioisomers of 4,5-dihydroisoxazolecarboxylates have been synt hesized in the 1,3-dipolar intermolecular cycloaddition and subjected to en zymatic hydrolysis by alpha-chymotrypsin from bovine pancreas (type IT) and to microbial hydrolysis by an Aspergillus niger fungus. For some compounds this hydrolysis time led to the obtaining of a racemic mixture, and for ot hers the reaction was enantioselective.
