Beschreibung / Inhaltsverzeichnis:
Hydrolysis and methanolysis of Avilamycin C yielded a series of mono- and oligosaccharide-like products, which were, with one exception, identical with degradation products of flambamycin. Instead of evalose (6-deoxy-3-methyl-D-mannose), a building stone of Flambamycin and Everninomicin B, evermicose (2, 6-dideoxy-3-methyl-D-mannose) was identified as a constituent of the Avilamycins. This sugar was known as a degradation product of the Everninomicins C and D. From the degradation results a structure of Avilamycin A was postulated which differs from that of Flambamycin only by the lack of a hydroxyl group in position 2 of the evalose residue. This hypothesis was confirmed by a careful 1H- and 13C-NMR. study.
