The preparation of benzazepinoindoles, fused heterocycles with a benzazepine moiety, was accomplished through an intramolecular 7-endo-tring Pictet-Spengler cyclization. The precursors comprising C-3- or C-2-linked o-aminobenzyl-indoles required for the c

Both cryptolepine 1 and cryptotackieine 3 have been synthesized from 1,3-bis(2-nitrophenyl)propan-2-one. The approach to 1 involved reduction of the NO2 groups, oxidative cyclization with PhI(OAc)2, and N-methylation, whereas 3 was obtained via bromination, Favorskii rearrangement, reduction (in situ cyclization), and N-methylation.
