摘要

Abstract

5-Aryl-1H-pyrrole-2,3-diones reacted with amidoximes to give enamines containing a 1,2,4-oxadi­azole fragment that are potential precursors to novel 1H-pyrrole-2,3-diones. The described reaction is the first example of recyclization of 4-unsubstitued 5-aryl-1H-pyrrole-2,3-diones by the action of 1,4-binucleophiles.
