Popis:	N-Boc/MOM-protected furoindolones, synthesized in four steps, have been successfully employed in the Hauser annulations with Michael acceptors to provide a new synthesis of carbazole-1,4-quinones. This methodology works well with a number of acceptors, and constitutes an efficient route for the synthesis of benzo[b]carbazoloquinones. The nature of N-protection of the synthons plays a crucial role in the success of annulations.
