Fm. Moghaddam et al., Water promoted Michael addition of secondary amines to alpha,beta-unsaturated carbonyl compounds under microwave irradiation, SYN COMMUN, 30(4), 2000, pp. 643-650
A rapid Michael addition of secondary amines to cc,P-unsaturated carbonyl c
ompounds has been achieved in good to excellent yields in the presence of w
ater under microwave irradiation. In the absence of water and under convent
ional method the reaction does not proceed or take place in very low yield
after a long reaction time.
