Cn. Ocallaghan et al., FORMATION OF POLYSUBSTITUTED PYRIDIN-2-ONE DERIVATIVES BY MICHAEL ADDITION OF 3-OXOBUTANAMIDE TO ALPHA,BETA-ETHYLENIC KETONES AND AMIDES, Journal of chemical research. Synopses, (2), 1997, pp. 50-51
Reaction of 3-oxobutanamide with 4-phenylbut-3-en-2-one and with 3-ary
l-2-cyanoprop-2-enamides and related compounds affords new di, tetra-
and hexa-hydropyridin-2-one derivatives, the degree of unsaturation of
the product depending on the experimental conditions.
