We describe an expeditious enantioselective total synthesis of the acetylenic marine natural products (R)-strongylodiols A and B. Central to the strategy is the use of Zn(OTf)2, amine base, and N-methyl ephedrine to mediate the direct addition of a 1,3-diyne to two long-chain aliphatic aldehydes in useful selectivities and yields.
我们描述了炔属海洋天然产物(R)-强甘油二醇A和B的快速对映选择性合成。该策略的核心是使用Zn(OTf)2,胺碱和N-甲基麻黄碱来介导直接添加1,3-二炔对两个长链脂族醛的选择性和收率很高。
