Specific features of the interaction of fervenulin and its 4-N-oxide with C-nucleophiles: Structural and spectroscopic characteristics of molecular complexes and covalent adducts with indoles

Abstract

Experimental data on the chemical transformations of the antibiotic fervenulin and its analogs have been analyzed and compared to the results of recent physicochemical investigations. Crystals of donor -acceptor complexes of fervenulin and its 4-N-oxide with indoles have been obtained, 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 fervenulin molecule is obtained.
