Synthesis in a stage of N-methoxyindolinones, N-methoxymaleimides and maleic anhydrides starting from α-halogen hydroxamic acids

α-Halo hydroxamic acids were used in the synthesis of N-methoxyindolinones, symmetric and dissymmetric N-methoxymaleimides in good yields. The hydrolysis of N-methoxymaleimides constitues a new and good route to maleic anhydrides.

The Chemistry of 3-(α-Cyanobenzylidene)-1-phenyltriazenes and Their Conversion to Diarylmaleimides and Phenanthrene-9,10-dicarboximides

3-(α-Cyanobenzylidene)-1-phenyltriazine (3a), the product of thermolysis of 5-azido-1,4-diphenyl-1,2,3-triazole (2), is attacked by nucleophilic reagents at the azomethine carbon.Alcohols and phenol give rise to acetals of the N-phenylamidine of phenylgly

SYNTHESE DE N-AMINO MALEIMIDES ET D'ANHYDRIDES MALEIQUES DISUBSTITUES A PARTIR D'α-HALOGENO HYDRAZIDES. ETUDE DU MECANISME DE LA REACTION.

α-Halohydrazides react with 2-aminopyridine to give symmetrically substituted N-aminomaleimides.We have shown that this reaction proceeds through the formation of 4-hydroxyimidazopyridines.This result opens a new route to dissymetrically substituted N-aminomaleimides.The hydrolysis of N-aminomaleimides is a grood route to substituted maleic anhydrides.
