The preparation of lividomycin B analogues, the title pseudotetrasaccharides, is described. Condensation of 6-azido-2,3,4-tri-<I>O</I>-benzyl-6-deoxy-L-idopyranosyl chloride with 4′,6′-di-<I>O</I>-benzoyl-5-<I>O</I>-(5-<I>O</I>-benzoyl-β-D-ribofuranosyl)-3,2′-bis(<I>N</I>-benzyloxycarbonyl)-1-<I>N</I>:6-<I>O</I>-carbonyl-3′-deoxyparomamine was followed by deblocking and reduction of the azido groups. Structure determinations and the antibacterial activities of the products are described.
