The oxirane ring of the dianhydro sugar 2 obtained from levoglucosan (1,6-anhydro-β-D-glucose) is opened regioselectively with organometallic carbon nucleophiles and its application to an asymmetric synthesis of the C1–C5 segment 9 together with the C9-C15 unit 18 of 6-deoxyerythronolide B 1 is described.
