  A simple and stereodivergent strategy for the synthesis of 3′-C-branched 2′,3′-dideoxynucleosides exploiting (Z)-but-2-en-1,4-diol and (R)-2,3-cyclohexylideneglyceraldehyde

  摘要：

  Barbier type additions of allylic bromide 4, derived from (Z)-but-2-en-1,4-diol 2 to (R)-2,3-cyclohexylideneglyceraldehyde 1 were performed through mediation with Zn employing Luche's procedure and also with low valent Cu, Co, and Fe which were produced via bimetal redox strategy in THF to afford 5c,d as the major products. From these, 5a,b were prepared following an oxidation-reduction protocol. Compound 5c was exploited as a representative starting material to develop a simple and inexpensive strategy toward the synthesis of 3'-C-branched 2',3'-dideoxynucleosides having stereodiversity at 3'- and 4'-positions.
