The biomimetic syntheses of bipleiophylline, one of the most complex monoterpene indole alkaloids, and voacalgine A, its biosynthetic precursor, have been achieved from pleiocarpamine starting material. The development of a divergent oxidative coupling for the formation of the benzofuro[2,3-b]indolenine and isochromano[3,4-b]indolenine moieties was key to this accomplishment.
