| Abstract: | It was shown that recyclization of enaminocarbonyl compounds in acid media affords pyrrolinone derivatives. 2-Methylthio-4-oxopyrroline-1-oxide reacts with NaBH4 exclusively at the carbonyl group- and with methylmagnesium iodide, at the nitrone group- with substitution of the methylthiol group for a methyl group.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 437–443, February, 1991. |
