  General Access to Iminosugar C-Glycoside Building Blocks by Means of Cross-Metathesis:  A Gateway to Glycoconjugate Mimetics

  摘要：

  [GRAPHICS]Cross-metathesis reactions of alpha-1-C-allyl-1-deoxynojirimycin derivatives 7a,b and various functionalized alkenes mediated by Grubbs's catalyst 3 are reported. The reactions showed reasonable to very good yields and excellent E/Z selectivity. This methodology allows the efficient and convergent synthesis of iminosugar C-glycosides with a great degree of structural diversity in the aglycone, opening the way to a variety of new glycoconjugate mimetics of biological interest.
