N-(2-Pyridyl)amides of 4-R-2-alkoxy-4-arylcrotonic acids and 3-alkoxy-3-aroylmethyl-2-oxo-2,3-dihydroimidazo[1,2-a]pyridines have been synthesized by the interaction of N-(2-pyridyl)amides of 4-aryl-2,4-dioxobutyric acids with diazoalkanes. The structure and mechanism of formation of the products are discussed.
