Tomaymycin (2) and oxotomaymycin (3) are antibiotics isolated from Streptomyces achromogenes var. Tomaymycetics. The structure of tomaymycin (2) was determined by degradation reactions together with spectral analysis and by synthesis of the important derivative (8b) containing the basic skeleton of the antibiotic. The structure of oxotomaymycin (3) was also established by chemical correlation to the derivative (7a) of tomaymycin.
