Studies directed towards the synthesis of miharamycin B

Abstract The northern part of Miharamycin B which differs from the natural product by the absence of a 2-carbon branched chain in the sugar moiety, was prepared by a sequence of selective transformations from methyl 2,3,4-tri-O-benzyl-α-D-gluco-hexodialdo-1,5-pyranoside 3 . The key step is a regioselective glycosylation of 2-aminopurine.
