Особенности взаимодействий фервенулина и его 4-N-оксида с C-нуклеофилами: структура и спектральные характеристики молекулярных комплексов и ковалентных аддуктов с индолами

Experimental data on chemical transformations of the antibiotic fervenuline and its analogs have been analyzed and compared with the results of recent physicochemical investigations. The crystals of donor - acceptor complexes of fervenuline and its 4-N-oxide with indoles have been grown, their IR spectra have been studied, and their X-ray structure analysis was performed for the first time. Information concerning the reaction sites of the fervenuline molecule is obtained.
