A general asymmetric approach toward cis-epoxypolyynes is described using optically pure (2R, 3S)-5-bromo-2,3-epoxy-4-pentyn-1-ol 1a as the key intermediate. From this intermediate, the synthesis of 2 epoxy polyyne natural products was carried out in 6 steps with a 42% overall yield.
描述了使用光学纯的(2R,3S)-5-溴-2,3-环氧-4-戊炔-1-醇1a作为关键中间体的通用的不对称方法。从该中间体以6个步骤进行了2种环氧聚炔天然产物的合成,总收率为42%。
