Abstract

An efficient synthesis of dimethyl tripartin as a synthetic precursor of natural product tripartin, the first natural specific inhibitor of histone H3 lysine 9 demethylase KDM4, is described. The synthesis of dimethyl tripartin was achieved in a six-step longest linear sequence starting from commercially available 3,5-dimethoxy benzaldehyde with 21% overall yield, using ClTi(O Pr)-mediated dichloromethine insertion as the key step.

摘要

本文描述了一种高效合成二甲基三帕汀的方法,它是天然产物三帕汀的合成前体,三帕汀是组蛋白H3赖氨酸9去甲基化酶KDM4的首个天然特异性抑制剂。二甲基三帕汀的合成从市售的3,5-二甲氧基苯甲醛开始,以六步最长线性序列完成,总产率为21%,使用ClTi(O Pr)介导的二氯甲烷插入作为关键步骤。
