Abstract
Chiral amines are resolved by selectively reacting an enantiomer of the amine with an alkyl ester in the presence of an enantioselective lipase enzyme to produce an amide of that enantiomer and separating it from the unreacted enantiomer, the alkyl group of the ester being an isoalkyl group. Isobutyl and especially isopropyl groups are preferred.
