Abstract: | The cyclization of the di(phenylhydrazone) of methyl -phenyl- , -dioxobutyrate with hydrazines has given phenylhydrazones of methyl indol-2-ylglyoxylates, which have been reduced to methyl -aminoindol-2-ylacetates. Some reactions of these compounds have been studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1040–1042, August, 1973. |
