Abstract

Abstract Epoxidation of 1-Benzoyl-1, 2, 2a, 3-tetrahydrobenz [cd] indole (4a) proceeded smoothly with metachloroperbenzoic acid with high exo diastereoselectivity (de= 96%) and chemical yield (97%). The basis for this selectivity was probed with substituent effects, and was extended to other oxidation media.
