Addition products of 2-(N-arylformimidoyl)pyridines and carbanions, and their reduction to octahydroindolizine derivatives
Abstract
The reactions of 2-(N-arylformimidoyl)pyridines with a number of active methylene compounds have been investigated. Reduction of the products gave octahydroindolizine derivatives, some of which were also prepared by other routes. The interaction of 2-(N-phenylformimidoyl)pyridine and diethyl succinate gave an octahydropyrrolo[3,4-c]pyrrole.
