Abstract

Abstract 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.
