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.
已经开发了一种简单的一锅法,用于将2-羟基-2-(2'-羟基-芳基)-1,3-茚满二酮转化为4-取代的苯并恶嗪酮。该过程构成有趣的酸催化重排,然后与羟胺缩合。
