An efficient synthesis of polyfunctionalized pyrroles by three-component reaction of arylglyoxals, Meldrum’s acid and ethyl 2-chloro-3-(arylamino)but-2-enoates
A fast and convenient method for synthesis of some new functionalized pyrrole derivatives have been described via a three-component reaction between arylglyoxals, Meldrum’sacid and ethyl 2-chloro-3-(arylamino)but-2-enoate derivatives in excellent yields. When a mixture of arylglyoxal, Meldrum’sacid and ethyl 2-chloro-3-(arylamino)but-2-enoats were stirred in ethanol as a green solvent at room temperature
