2010 m. Nr. 1 Synthesis of a new bridged heterocyclic system: 5a,12a-propanoindolo[2,3-c][2]benzazepine
Reaction of penta[b]indolylmagnesium iodide with 2-bromomethylbenzonitrile afforded 8b-(2-cyanobenzyl)-1,2,3,8b-tetrahydrocyclopenta[b]indole which was alkylated with iodomethane and gave the corresponding N-methyl-8b-(2-cyanobenzyl)penta[b]indolium iodide. Cyclization of the latter to new bridged heterocycles containing 5a,12-propanoindolo[2,3-c][2]benzazepine ring system has been studied. Keywords: heterocycles, penta[b]indoles, Grignard derivatives, 2-bromomethylbenzonitrile, 5a,12a-propanoindolo[2,3-c][2]benzazepine |
