摘要：

A simple one-pot procedure for the conversion of 2-hydroxy-2-(2'-hydroxy-aryl)-1,3-indanediones to 4-substituted benzoxazinones has been developed. The process constitutes an interesting acid-catalyzed rearrangement followed by condensation with hydroxylamine. (C) 2011 Elsevier Ltd. All rights reserved.
