Biologically Potent L ‐Hexoses and 6‐Deoxy‐ L ‐Hexoses: Their Syntheses and Applications

This account describes our recent work in the development of new methodologies to prepare rare and biologically potent L ‐hexoses and 6‐deoxy‐ L ‐hexoses, from cheapest D ‐glucose, via L ‐hexofuranoses and 1,6‐anhydro‐β‐ L ‐hexopyranoses as key building blocks. Their applications in the syntheses of heparin oligosaccharides, the carbohydrate moiety of bleomycin A 2 , and L ‐acovenose are also summarized here.
