FIVE-MEMBERED 2,3-DIOXO HETEROCYCLES. 2. SYNTHESIS AND -SIGMATROPIC REARRANGEMENT OF 4-ACYL-3-DIPHENYLMETHOXY-1,5-DIPHENYL-2,5-DIHYDROPYRROL-2-ONES

4-Acyl-1,5-diphenyltetrahydropyrrole-2,3-diones react with diphenyldiazomethane to give O-alkylation products, which upon heating undergo -sigmatropic suprasurface rearrangement to form 4--1,5-diphenyltetrahydropyrrole-2,3-diones.
