The synthesis of five different 5,6-dideoxyhex-5-enofuranosides (5, 7, 9 and 11) proceeds in 30-60X overall yield in two steps from consnercially available 1-01-mefhyT pyrafi"osides by reductive B-elimination of the intermediate 6-bromo-6-deoxypyranosiaes. We desired a test of the idea that reducti
