The monosaccharide component (α and β-anomer) of the E Ring of calicheamicin γ1(I) and esperamicin A1 has been synthetized by an efficient and improved stereoselective procedure starting from methyl 2-deoxy-α- and β-D-ribopyranoside. The synthetic procedure makes use, in each case, of a cyclic sulphate and of the regioselective ring opening of an intermediate activated aziridine.
