A stereoselective synthesis of (4E,7S)-(-)-7-methoxydodec-4-enoic acid has been accomplished in eight steps from hexanal in 24% overall yield. The key steps involved the catalytic asymmetric allylation of hexanal and the coupling reaction of a chiral alkyne and a protected bromide in the presence of t-BuLi.
由己醛通过八步立体选择性合成(4E,7S)-(-)-7-甲氧基十二-4-烯酸,总产率为24%。关键步骤涉及己醛的催化不对称烯丙基化以及手性炔烃和受保护的溴化物在叔丁基锂存在下的偶联反应。
