[Oleandomycin and its natural and synthetic analogs. I. Dissociative ionization of oleandomycin and its derivatives]
Abstract:
Regularities of dissociative ionization of compounds belonging to the oleandomycin group were studied. Mass spectra of oleandomycin and some of its derivatives including anhydrooleandomycin, oleandomycin chlorhydrine, desoleandomycin, oleandomycin oxide, trimethylsilyl and acetyl derivatives were analyzed comparatively. Directions of disintegration with breakage of the glycoside bonds, macrolactone and carbon cycles were detected. The data are useful in structural analysis of not described oleandomycin-related compounds formed during biosynthesis and isolation of the main product.
