efficient total synthesis of botryolide B was achieved in 9 longest linear steps with 22% overall yield via esterification of a carboxylic acid with an alcohol fragment and a ring closing metathesis (RCM) reaction as pivotal steps to construct the macrolactone ring system. Our novel approach for the synthesis of the 2-alkene-1,5-diol fragment was achieved by a ring closing metathesis reaction followed
通过羧酸与醇片段的酯化反应和闭环易位(RCM)反应,作为构建大内酯环体系的关键步骤,可以在9个最长的线性步骤中高效地合成Botryolide B,总产率为22%。通过闭环易位反应,然后采用还原性开放策略,可以实现合成2-烯烃-1,5-二醇片段的新颖方法,而羧酸片段则可从市售(R)-(+)处获得。 -α-羟基-γ-丁内酯分三个步骤。
