Ethyl 2,3-anhydro-4,5:6,7-di-O-isopropylidene-D-arabino-heptonate was prepared for the first time by the Darzens reaction from 2,3:4,5-di-O-isopropylidene-D-arabinose and ethyl chloroacetate under the action of metallic sodium in p-xylene. The reaction gives a number of by-products, including ethyl 3-chloro-2-deoxy-3-hydroxy-4,5:6,7-di-O-isopropylidene-D-arabino-heptonate.
