A 12-step total synthesis of the tricyclic heteroaromatic marine metabolite ageladine A has been achieved using a 6 pi-azaelectrocyclization and a Suzuki-Miyaura coupling of N-Boc-pyrrole-2-boronic acid with a chloropyridine as key steps.

A 12-step synthesis of the angiogenesis inhibitory marine metabolite ageladine A is reported. The key steps include a 6π-1-azatriene electrocyclization for formation of the pyridine ring and a Suzuki−Miyaura coupling of N-Boc-pyrrole-2-boronic acid with a chloroimidazopyridine. In addition, an assessment of the biological activity of a variety of synthetic analogues of ageladine A prepared during this
