Abstract

Fused pyridine derivatives R 0450 Condensed Isoquinolines. Part 18. Enamine Properties of Benzimidazo[1,2-b]isoquinolin-11(5H)-one in the Michael Reaction. -Reaction of the title benzimidazoisoquinolinone (I) with activated olefins yields benzimidazobenzonaphthyridine derivatives via an initial Michael reaction followed by intramolecular heterocyclization. -(POTIKHA, L.
