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.

The synthesis of the marine alkaloid hyellazole and the non-natural regioisomer isohyellazole is reported starting from the tricarbonyliron-complexed cyclohexadienylium cation and the fully functionalized arylamines by electrophilic aromatic substitution and oxidative cyclization.

The marine alkaloid hyellazole has been synthesized in a convergent manner from the tricarbonyliron-complexed cyclohexadienylium cation and a fully functionalized arylamine by an electrophilic aromatic substitution and subsequent oxidative cyclization.
