Abstract
Racemomycin-C was semi-synthesized from racemomycin-A by condensation with diZ-β-lysine-OSU followed by catalytic hydrogenation. Racemomycins B, D and E were also prepared in the similar manner. Among these antibiotics, racemomycin-B containing three β-lysine residues in one molecule showed the strongest antibacterial activity against B. subtilis.
