Intramolecular palladium-catalyzed cyclization of methyl 1-(2- bromobenzyl)indole-2-carboxylates: Synthesis of pratosine and hippadine

Miki, Yasuyoshi,Shirokoshi, Hideaki,Matsushita, Ko-ichi

, p. 4347 - 4348 (1999)

Palladium-catalyzed cyclization of methyl 1-(2-bromo-4,5-dimethoxy- benzyl)indole-2-carboxylate in the presence of potassium acetate in hot 1,4- dioxane gave a 7H-pyrrolo[3,2,1-de]phenanthridine derivative, which was converted to pratosine in four steps.
