Abstract
1409935 # - Carboline - derived tetracyclic compounds VSESOJUZNY NAUCHNOISSLEDOVATELSKY KHIMIKO - FARMATSEVTICHESKY INSTITUT IMENI S ORDZHONIKIDZE 22 Nov 1973 54150/73 Heading C2C [Also in Division A5] The invention comprises compounds of Formula I and their acid addition salts, wherein R is H, alkyl or alkoxy, R<SP>1</SP> is alkyl and m, n are each 2 or 3; and a process for making them by cyclizing the lactams (III) with POCl 3 and decomposing the thus formed salts (IV) with alkali or an alkanol.
