The synthesis of (Z)-4-oxo-4-(arylamino)but-2-enoic acid (4) derivatives containing structural characteristics that can be used for the synthesis of several active molecules, is presented. Some of the butenoic acid derivatives (4a, 4c, 4e, 4i, 4j, 4k) are

This article described the synthesis of poly N-arylmaleimides and copolymaleimides. The maleimides monomer N- (2-nitrophenyl)maleimide (2-NPMI), N-(3-nitrophenyl)maleimide (3-NPMI) and N-(4-nitrophenyl)maleimide (4-NPMI) were prepared from corresponding s

Triphenylphosphine (TPP) in refluxing methanol effectively reduces maleimides 1a-g to the corresponding succinimides 2a-g in good yields. It was observed that some maleimides obtained from aromatic halogen compounds 1h-j were transformed into the corresponding succinamic acid methyl esters 3a-c by this reaction.
