chain length was investigated for the enantioselective hydrolysis of racemic 4-arylbut-3-en-2-yl esters using Lecitase™ Ultra (LU). Immobilized preparations of the Lecitase™ Ultra enzyme had significantly higher activity and enantioselectivity than the free enzyme, particularly for 4-phenylbut-3-en-2-yl butyrate as the substrate. Moreover, the kineticresolution with the immobilized enzyme was achieved
Kinetic resolution of (E)-4-(2′,5′-dimethylphenyl)-but-3-en-2-ol and (E)-4-(benzo[d][1′,3′]dioxol-5′-yl)-but-3-en-2-ol through lipase-catalyzed transesterification
respectively. The kinetic resolution of (E)-4-(benzo[d][1′,3′]dioxol-5′-yl)-but-3-en-2-ol using isopropenyl acetate and CAL-B after 1 h gave (−)-(S)-alcohol (ee = 99%) and (+)-(R)-acetate (ee = 91%) in yields of 44% and 46%, respectively. (+)-(R)-Alcohols were obtained by the hydrolysis of the corresponding esters. Except for (+)-(R,E)-4-(benzo[d][1′,3′]dioxol-5′-yl)-but-3-en-2-ol, all enantiomerically
