A considerably improved iron-mediated synthesis leads to the marine carbazole alkaloid hyellazole on large scale in eight steps and 63% overall yield from 2,6-dimethoxytoluene. The first conversion of hyellazole into 6-chlorohyellazole has been achieved along with remarkably regiospecific halogenation reactions.
铁介导的合成得到显着改善,可通过 8 个步骤大规模生产海洋咔唑生物碱 hyellazole,2,6-二甲氧基甲苯的总产率为 63%。随着显着的区域特异性卤化反应,已经实现了hyellazole到6-chlorohyellazole的第一次转化。
