摘要：

A three-step reaction sequence starting from a ribonucleoside to give the corresponding 5'-O-acyl-2',3'-didehydro-2',3'-dideoxynucleoside is described. The key intermediate is the bromoacetate, made by reaction of the 2',3'-methoxyethylidene nucleoside with acetyl bromide. Reductive elimination of the bromoacetate using a zinc-copper couple furnishes the desired compounds in good overall yield.
