asymmetric synthesis of 14-methyl-1-octadecene, the sex pheromone of the peach leafminer moth has been achieved. The target molecule was synthesized in six linear steps and in 30.3% overall yield from commercially available hexanoyl chloride, (S)-4-benzyloxazolidin-2-one and 1,9-nonanediol. The hexanoyl chloride was connected with (S)-4-benzyloxazolidin-2-one, and with the induction of the chiral oxazolidinone
桃潜叶蛾的性信息素 14-methyl-1-octadecene 的不对称合成已经实现。目标分子是由市售己酰氯、(S)-4-benzyloxazolidin-2-one 和 1,9-nonanediol 以六个线性步骤合成的,总产率为 30.3%。己酰氯与(S)-4-benzyloxazolidin-2-one相连,在手性恶唑烷酮助剂的诱导下,经手性甲基化、LAH还原、甲苯磺酰化后,得到高立体选择性的手性关键中间体5。1,9-壬二醇经过选择性溴化、THP 保护并进行 Li2CuCl4 介导的 CC 偶联,得到 C12 中间体。在两部分进行第二次 Li2CuCl4 介导的 CC 偶联后,获得目标分子 (S)-14-methyl-1-octadecene。
