Abstract

In polyphosphoric acid, the Fischer indolization of 6‐arylhydrazono‐1,2,3,4,6,7,8,9‐octahydro‐11H‐pyrido‐[2,1‐b]quinazolin‐11‐ones, obtained from 1,2,3,4,6,7,8,9‐octahydro‐11H‐pyrido[2,1‐b]quinazolin‐11‐ones by three pathways, afforded substituted 1,2,3,4,7,8‐hexahydro‐5H‐13H‐indolo[2′,3′:3,4]pyrido[2,1‐b]quinazolin‐5‐ones in high yields. The structures of the 6‐substituted octahydropyridoquinazolinones and hexahydroindo‐lopyridoquinazolinones were characterized by uv, 1H and 13C nmr data.
