Synthèse en une étape de N-méthoxyindolinones, de N-méthoxymaléimides et d’anhydrides maléiques à partir d’acides hydroxamiques α-halogénés
摘要:
a-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. (c) 2005 Elsevier Ltd. All rights reserved.

α-halohydrazides react with 2-amino pyridine to give symetrically substituted N-amino maleimides. We have shown that this reaction proceeds through the formation of 4-hydroxy imidazopyridines. This result open a new route to dissymetrically substituted N-amino maleimides. The hydrolysis of N-amino maleimides is a good route to substituted maleic anhydrides.
