Abstract
Kinetic resolution of rac-Stiripentol, catalysed by lipase A from Candida antarctica by esterification with vinyl butanoate was performed with an E-value of 24. This allowed isolation of (3S)-Stiripentol with an ee of 86 % and the corresponding (3R)-butanoate with an ee of 87 %. Enzymatic hydrolysis of the ester product gave (3R)-Stiripentol with 94 % ee.
