general, efficient, and conceptually new approach to the total syntheses of marine-derived indole alkaloids, including (+/-)-flustramines A (1) and B (2), (+/-)-flustramides A (3) and B (4), and (+/-)-debromoflustramine B (5), is outlined. The keystep in the syntheses involves the conjugatedaddition of an organomagnesium species derived from prenyl bromide to 2-hydroxyindolenines. Compounds 1, 2, and
