(3Z,6Z,9S,10R)-9,10-Epoxy-3,6-henicosadiene (1) and (3Z,6Z,9S,10R)-9,10-epoxy-1,3,6-henicosatriene (5), pheromone components of the female fall webworm moth (Hyphantria cunea Drury), were synthesized by starting from (2S,3R)-2,3-epoxy-4-t-butyldimethylsilyloxy-1-butanol (8). Epoxide 8 was prepared by employing lipase-catalyzed asymmetric acetylation of (±)-8 as the key optical resolution step.
(3Z,6Z,9S,10R)-9,10-环氧-3,6-henicosadiene(1)和(3Z,6Z,9S,10R)-9,10-环氧-1,3,6-henicosatriene(5)、这些信息素是由 (2S,3R)-2,3-环氧-4-叔丁基二甲基
硅氧基-
1-丁醇 (8) 开始合成的。
环氧化物 8 是通过
脂肪酶催化的 (±)-8 不对称乙酰化作为关键的光学解析步骤制备的。
