Base-catalyzed reactions of substituted 1,4-naphthomethyIenequinoneimines, derivatives of 1l-methylene-5a,6,7,9a-tetrahydronaphtho[1',2':4,5]imidazo[l,2-a]pyridine, with compounds containing an active methylene group result in exchange of the methylene fragments. This reaction is an example of a new direction of nucleophilic attack in methylenequinpid systems.
