SOLVENT-FREE MICROWAVE MICHAEL ADDITION OF ISATIN AND ANILINE SCHIFF BASE OF ISATIN TO α,β-UNSATURATED ESTERS

The rapid, simple, microwave-assisted Michael addition of isatin and aniline Schiff base of isatin to a wide variety of alkyl and aryl acrylates in the presence of, tetrabutylammonium bromide (TBAB) and 1,4-diazabicyclo[2.2.2]octane (DABCO), under solvent-free conditions, is presented. Under these c...
