Application of 7- endo - trig Pictet,Spengler Cyclization to the Formation of the Benzazepine Ring: Synthesis of Benzazepinoindoles,

EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 9 2009
Sudhir K. Sharma
Abstract The preparation of benzazepinoindoles, fused heterocycles with a benzazepine moiety, was accomplished through an intramolecular 7- endo - trig Pictet,Spengler cyclization. The precursors comprising C-3- or C-2-linked o -aminobenzylindoles required for the cyclization were obtained either by treating indoles with o -nitrobenzyl bromide followed by reduction of the nitro group or by treating 2-nitrophenylacetic acid with DCC/DMAP followed by reduction of the aryl nitro functionality. Resulting substrates 5 and 6 were then subjected to the 7- endo - trig Pictet,Spengler reaction with a variety of aldehydes and ketones to furnish new polycyclic structures benzazepinoindoles.
