Studies in the indole series. Part VII. Indolo[1,7-ab][1]benzazepines and related compounds

Abstract

Methods of converting 10,11 -dihydrodibenz[-b,f]azepine into its N-amino-derivative are described, and the syntheses from the latter of indolo[1,7-ab][1]benzazepines by Fischer cyclisation of appropriate hydrazones are discussed. The polycyclic indoles have been converted into basic products by the Mannich reaction, and the indolic derivatives have been reduced with sodium and liquid ammonia to the corresponding indolines.
