  Palladium-mediated arylation of acetylated enones derived from glycals. 4. Synthesis of aryl-2-deoxy-.beta.-D-C-glycopyranosides

  摘要：

  The palladium-mediated arylation of the peracetylated glycal-derived enones 1, 2, and 3 afforded mixtures of C-glycosides containing an arylated enone (1a, 2a, or 3a) and an arylated ketone (1b, 2b, or 3b). A rationale for the formation of these compounds is given. Reduction of the arylated enones proceeds in a stereospecific manner, thus affording aryl 2-deoxy-beta-D-C-glycopyranosides in high yield.
