The 5-0-benzoyl derivatives 3 and 4 derived from 1,6-anhydro-β-D-mannpfuranose and -α-L-gulofuranose are suitable educts for the preparation of the isomeric olefins 7 and 8 by Corey-Winter elimination via the thionocarbonates 5 and 6, respectively. 8 was prepared in higher yields also from 5-α-Benzoyl-1,6-anhydro-α-L-talofuranose (14) via 15. Payne oxidation of the unsaturated compounds 7 and 8 gave the exo epoxides 9 and 10 with D-allo and L-talo configuration.
