The synthesis of both enantiomers of dodecyl rhamnospicamycin 2a and 2b, a rhamnose analogue of the naturally occurring combinatorial library spicamycin 1, are derived from L-rhamnose and methyl α-D-mannopyranoside, respectively. The L-(+)-enantiomer 2a c

The structures of tallysomycins A and B, two major components of a new antitumor antibiotic complex, have been determined. They are glycopeptide antibiotics structurally related to bleomycin: four amino acid moieties and a disaccharide fragment which are the constituents of bleomycin molecule are also present in the tallysomycins. Tallysomycins A and B contain two new amino acids and a unique amino sugar, 4-amino-4,6-dideoxy-L-talose, which have not been hitherto found in the phleomycin-bleomycin group of antibiotics. In addition tallysomycin A has an additional amino acid, L-β-lysine, and thus a longer peptide chain than bleomycin or tallysomycin B. Tallysomycins A and B have the same terminal amine moiety, spermidine.
