Abstract: | Bis(2-carbethoxy-5-indolyl) oxide was obtained by cyclization of ethyl pyruvate 4,4-diphenyloxydihydrazone. 5-Phenoxy-2-carbethoxyindole was also isolated from the reaction products. Saponification of these esters gave the corresponding acids, the thermal decarboxylation of which yielded di(S-indolyl) oxide and 5-phenoxyindole.See [1] for Communication 7.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 57–61, January, 1981. |
