  Synthesis of 2,6-Dideoxysugars via Ring-Closing Olefinic Metathesis

  摘要：

  graphicGrubbs' RuCl2(=CHPh)(PCy3)(2) (catalyst 1) and RuCl2(=CHPh)(PCy3)(IMess) (catalyst 2) complexes have been successfully utilized in the construction of beta,gamma-unsaturated delta-lactones containing various substitution patterns of methyl groups. Asymmetric dihydroxylation followed by reduction leads to 3,4-cis-dihydroxy-2,6-dideoxypyranoses, which have proven to play very important biological roles as key components of natural products.
