Reaction of N-vinylic phosphazenes with α,β-unsaturated ketones leads to the formation of pyridines derivedfrom β-amino acids in a regioselective fashion. The use of functionalized enones derivedfrom α-acylstyryl-carboxylates or -phosphonates affords biologically active asymmetrical and symmetrical dihydropyridines substituted with carboxylate or phosphonate groups including nitrendipine, felodipine
