Kinetic resolution of racemic 1-cyano-1-methylalkyl and alkenyl acetates has been achieved on incubation with IAM 4682, which hydolyzed selectively the ()-enantiomer, leaving behind the ()-enantiomer intact. The chiral 1-cyano-1-methyl-5-hexenyl acetate thus obtained was converted to ()-(−)-frontalin via unsaturated diol.
通过与IAM 4682孵育可以实现外消旋的1-氰基-1-甲基烷基和乙酸烯基酯的动力学拆分,IAM 4682选择性地水解(- )-对映体,而完整保留()-对映体。如此获得的手性1-氰基-1-甲基-5-甲基-5-己烯基乙酸酯经不饱和二醇转化为()-(-)-额叶蛋白。
