Abstract
Base-catalyzed one-pot cyclocondensation reactions of acryloyl and cinnamoyl chlorides with β-nitroenamine derivatives have been performed under mild conditions and target 7-substituted thiazolo-[3,2-a] or imidazolo-[1,2-a]pyridin-5-one derivatives were prepared successfully in moderate to good yields. The cyclization reactions may proceed via Michael addition followed by iminoketene-amide tautomerization in view of the products formed.
