significant pest in vineyards. We herein report the preparation of the two enantiomers of lavandulol and lavandulyl senecioate, starting from racemic lavandulol. The preparation is based on a two-cycle enzymatic transesterification of racemic lavandulol with vinyl acetate using Porcine pancreas lipase. High enantioselectivity was achieved while the preparation yielded (R)-lavandulol with 96.7% ee and (S)-lavandulol
(R)和(S)-lavandulol是化妆品工业和信息素研究中的重要化合物。(S)-lavandulyl的千里香酸酯最近被鉴定为藤粉虱的性信息素,该粉虱是葡萄园中的一种重要害虫。我们在此报告了从外消旋的lavandulol开始制备lavandulol和lavandulyl千里光酸酯的两种对映体的过程。该制备方法是使用猪胰脂肪酶,将消旋的lavandulol与乙酸乙烯酯进行两轮酶促酯基转移反应。实现了高对映选择性,同时该制剂产生了具有96.7%ee的(R)-lavandulol和具有92.6%ee的(S)-lavandulol。
