An alternative strategy has been developed for producing 3-azido-2,3,6-trideoxy-L-hexoses, protected forms of daunosamine, ristosamine, acosamine, and epi-daunosamine. This method involved BF3-OEt2-induced peroxidation of rhamnal to construct key intermediate alpha,beta-unsaturated lactone as the common precursor. After further derivatization, four 3-azido hexoses were successfully synthesized. (c) 2007 Elsevier Ltd. All rights reserved.
