  Glycosyl Transfer to Nitrogen via Cycloaddition

  摘要：

  [GRAPHICS]This letter describes the reduction to practice of a novel concept for functionalization of the anomeric carbon of carbohydrates with a nitrogen substituent. Thus, bisheterodienes with a thiono sulfur terminus and a sulfonylimine terminus are shown to undergo cycloaddition smoothly and stereoselectively to three different glycals.

  Retro Diels-Alder (RDA) reaction to form α-oxosulfines under very mild conditions. These reactive intermediates can be successfully trapped as dienophiles or as electron poor dienes in Inverse Electron Demand Diels-Alder reaction (IEDDA). The relationship between the structure of the starting sulfoxide, the geometry of the intermediate sulfine and the stereochemistry of the final cycloadduct have been
