Concept Introduction:

Michael reaction is the reaction between a Michael donor which acts as a nucleophile and a Michael acceptor.  Important condition for the Michael reaction to occur is the formation of stabilized nucleophile.  1,4-addition is known as Michael addition where the beta-keto compound acts as nucleophile.  General scheme for Michael reaction can be given as,
