Structures of murrafoline-B and -C, new binary carbazole alkaloids from Murraya euchrestifolia.

Abstract

The structures of murrafoline-B (1) and -C (5), new binary carbazole alkaloids from Murraya euchrestifolia hayata (Rutaceae), have been determined by spectral experiments, and dimerization of the monomeric carbazole alkaloids is discussed.
