“…7 Several synthetic reports for these vinyl ethers via dehydrohalogenation of 5-halogeno-furanose derivatives, 8 Bamford-Stevens rearrangement of 5-tosylhydrazono-furanose derivatives 9 and Wittig reaction of aldehydes with sugar-based triphenylphosphonium salts 10 have been reported in the literature. Attempts to elaborate the synthetic utility of these ethers in producing glycosides, 11 polyethers, 12 spiroketals 13 and related compounds 14 including heterocycles, 15 carbocyles, 16 and nucleosides 17 using coupling reactions, 18 radical processes 19 and cycloaddition reactions 20 have generated molecules of diverse nature. Nevertheless, the chemistry of these systems is less developed as compared to endocyclic vinyl ethers that allow regio-and stereoselective transformation, glycosylation as well as C-C and C-heteroatom bond formations at the anomeric centre.…”
