  The First Polymer-Assisted Solution-Phase Synthesis of Deoxyglycosides

  摘要：

  [GRAPHICS]A glycosylation protocol for the synthesis of 2-deoxyglycosides has been developed which is based on the use of polymer-bound reagents. Glycals are transformed into 2-iodoglycosyl acetates using polymer-bound bis(acetoxy)iodate(1) complex (1). Activation of the anomeric center is achieved by employing polymer-bound silyl triflate (2). In the presence of different glycosyl acceptors, 2-deoxy-2-iodoglycosides are generated in very good yields. Furthermore, it is shown that this method can be embedded in multistep sequences toward glycosylated testosterone and rhodinosyl-olivosyl-olivoside.
