An efficient synthesis of various model compounds 4a-e for the tricyclic core of popolophuanone E (1), a novel marine natural product, was accomplished; the method features highly regioselective annulation of the phenols 5a-e with the 2,3-dichloro-1,4-benzoquinones 7, 7c-e. Preliminary studies definitely demonstrated the feasibility of our designed synthetic strategy for 1 (the phenolic subunit I +
有效合成了新型海洋天然产物Popolophuanone E(1)的三环核心的各种模型化合物4a-e。该方法采用了酚的高度选择性环5A-E与2,3-二氯-1,4-苯醌7,图7C-E 。初步研究明确表明了我们设计的1合成策略(酚亚基I +醌亚基II→1)的可行性。
