Abstract
The three-component reaction of triphenylphosphine, dimethyl acetylenedicarboxylate and 3-arylamino-1-methyl-1H-pyrrole-2,5-diones in CH2Cl2 at room temperature resulted in functionalized 3-(triphenyl-λ5-phosphanylidene)succinates in nearly quantitative yields. However, tri(n-butyl)phosphine promoted reaction of dialkyl acetylenedicarboxylates and 3-arylamino-1-methyl-1H-pyrrole-2,5-diones in CH2Cl2 afforded functionalized pyrrolo[3,4-b]pyridine-4-carboxylates in satisfactory yields.
