SYNTHESIS OF 2,3-DIALKOXY-1H-PYRROLE VIA REDUCTION OF DIOXOPYRROLINE WITH SODIUM HYDROSULFITE

Reduction of 1H-pyrrole-2,3-dione (3 and 7) with sodium hydrosulfite took place selectively in a 1,4-manner.Methylation of the product with diazomethane gave 1,5-dihydro-3-methoxy-2H-pyrrol-2-one (5 and 8) in good yield.Treatment of the methyl ether (5 or

Dioxopyrrolines. XXIX. Solvolytic Behavior of 3-Ethoxycarbonyl-2-phenyl-Δ2-pyrroline-4,5-diones in Protic Solvents

The solvolytic behavior of 3-ethoxycarbonyl-2-phenyl-Δ2-4,5-diones 7 depends on the N-substituents.On treatment with ethanol or methanol, the NH derivative 7a afforded the corresponding keto ester 9, a product of C5-lactam carbonyl a
