The preparation of polycyclic heterocycles with one or more nitrogen atoms and different binding angles by a domino reaction is described, These compounds (4-6, 8a-b) are formed by the reaction of β-amino ketone hydrochlorides 1 or 2 (Mannich bases) with ketones 3. Especially the synthesis of the terpyridines 8a and 8b in a double domino reaction is very useful (yield 70 and 59%) and opens a route to torands. VCH Verlagsgesellschaft mbH, 1996.
