Reaction of enamino-phosphonium salts derived from β-aminoacids with α,β-unsaturated aldehydes leads to the formation of symmetrical dihydropyridines. Moreover, no symmetrical dihydropyridines can be obtained by the reaction of enamino-phosphonium salts derived from of N-vinylic phosphazenes with α,β-unsaturated ketones.
