| Abstract: | It is shown that 3,8-diformyl-1H,6H-pyrrolo2,3-e]indole dioxime is produced in the form of a mixture of geometrical isomers, which were separated by column chromatography. It was established by PMR spectroscopy that they have anti,syn and syn,syn configurations with a cisoid-transoid conformation of the side chains.See 1, 2] for Communications 2 and 3.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 646–648, May, 1981. |
