We describe herein an efficient synthesis of all the four stereoisomers of tarchonanthuslactone from (R)-3-hydroxy butanoate, easily prepared from l-threonine. The approach involves the use of a β,γ-unsaturated δ-lactone as an intermediate, obtained via a Kulinkovich reaction followed by a ring-closing metathesis strategy.
我们在本文中描述了从(R)-3-羟基丁酸酯容易地由1-苏氨酸制备的沙丁鱼胶内酯的所有四个立体异构体的有效合成。该方法涉及使用β,γ-不饱和δ-内酯作为中间体,该中间体是通过库林科维奇反应获得的,然后采用闭环复分解策略。
