  Chain Extension of Sugar δ-Lactones with the Enolate of tert-Butyl Bromoacetate and Elaboration into Functionalized C-Ketosides, C-Glycosides, and C-Glucosyl Glycines

  摘要：

  [GRAPHICS]We describe the synthesis of a series of exocyclic sugar epoxides 1 prepared in a one-step procedure from sugar delta -lactones with the enolate of tert-butyl bromoacetate. Ring opening of the sugar oxiranes provides C-ketosides while reduction affords functionalized C-glycosides bearing an a-hydroxy ester moiety. The a-hydroxy ester can be converted into C-glucosyl glycine analogues 2.
