概要

• 論文の詳細を見る

• Optically pure n-tert. -leucine was obtained by the enzymatic hydrolysis of (±)-N-acetyl-tert. leucine chloroethyl ester after about 50% conversion, this being catalyzed by a protease from Bacillus licheniformis (Alcalase^[○!R]), and subsequent acidic saponification of the recovered ester. Among the methyl, ethyl, octyl, chloroethyl and trichloroethyl esters, the chloroethyl ester exhibited the highest rate of hydrolysis.
