ADDITION REGIOSELECTIVE D'ORGANOMETALLIQUES α-INSATURES OU α-FONCTIONNELS AU CHLORURE DE N-ETHOXYCARBONYLPYRIDINIUM: SYNTHESE DE DIHYDRO-1,2 (OU-1,4)PYRIDINES 2-(OU-4)SUBSTITUTEES.

Article abstract of DOI:10.1016/S0040-4039(00)98503-4

α-unsaturated and α-functional organometallics easily react with 1-ethoxycarbonylpyridinium chloride to lead to 1,2 (or 1,4) substituted dihydropyridines.From these dihydropyridines, either pyridines or piperidines can be prepared.
