Pyridines are readily annelated with nitriles of α,β-acetylenic γ-hydroxyacids under mild conditions (ambient temperature, no catalyst, no solvent) to give new condensed dihydropyridine systems, 4-cyanomethylidene-1,3-oxazolidine[3,2-a]-1,2-dihydropyridines in 75-83% yields. © 2002 Elsevier Science Ltd.
