The asymmetric synthesis of pentacyclic compound 13, a known intermediate in the synthesis of l-acetylaspidospermidine, was conducted via the condensation of 2-hydroxytryptamine with chiral C9 lactone 9, readily available from triol 4.
通过2-羟基色胺与手性C9内酯9的缩合反应进行五环化合物13的不对称合成,该化合物是合成1-乙酰基aspidospermidine的已知中间体,可以很容易地从三元醇4中获得。
