A convergent total synthesis of the marine sponge alkaloid ageladine A via a strategic 6π-2-azatriene electrocyclization

A second generation total synthesis of the marine sponge metabolite ageladine A utilizing a biogenetically inspired 6π-2-azaelectrocyclization of triene 34 as the key step is performed to construct the imidazopyridine core of the metabolite.
