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.

The nucleophilic ring opening of gem-dicyanoepoxides by LiBr or Li2NiBr4, in the presence of hydroxylamine derivatives leads to new α-halo hydroxamicacids. These compounds has been used in the synthesis of α-functionalized hydroxamicacids, α-hydroxy and α-amino acids in good yields.
