摘要：
New reactions of vinyliminophosphoranes with aldehydes involving an initial nucleophilic attack of the beta-carbon atom of the vinyl side chain on the carbonylic carbon atom is reported. The resulting betaines undergo either intra- or intermolecular cyclization to give pyridines or dihydropyridines.
