Abstract

The reaction of α-cyano-β-dimethylaminocrotonic acid amide with acetals of dimethyl acetamide and N-methylbutyro-, -valero-, and -caprolactams gave enaminoacrylamidines, cyclization of which gave 3-cyano-6-dimethylamino-2-pyridone and the corresponding pyrrolo-,pyrido-, and azepino[2,3-b]pyridine derivatives.
