  An expeditious hydroxyamidation of carboxylic acids

  摘要：

  Capitalizing on in situ activation with the cyclic phosphonic anhydride PPAA (1), the conversion of carboxylic acids into hydroxamic acids has been reduced to an experimentally simple one-pot operation that addresses the issue of polyacylation Without resorting to a large excess of hydroxylamine or to protection. Scope and selectivity were satisfactory with a wide range of substrates, including of alpha,beta-tinsaturated acids and hydroxyacids. (c) 2005 Elsevier Ltd. All rights reserved.
