Abstract
The michael adducts 2a, b were obtained from the reaction of the phenylacelyl derivative 1 with benzadehyde and p-anisaldehyde and p-anisaldehyde respectively. 2a and 2b were subjected to react with cyanoethanoic acid hydrazide, malononitrile, cyanothioacetamide, cyanoacetamide and 1, 1, 3-tricyano-2-amino propene to yield 4a-h and 5a, b respecitively. Hydrogen peroxide oxidation of 2a, b gave the aurone derivative 6a, b. The pyone derivatives 8a, b were obtained from 2a, b by addition of chioroacetyl chioride followed by dehydrochlorination.
