Synthesis of 2'-C-α-methyl-2',3'-dideoxynucleosides

A general method for the synthesis of 2'-C-α-methyl-2',3'-dideoxynucleosides is presented. Stereofacial selectivity of the 2-C-methylation reaction of γ-lactone has been investigated, in which the presence of a bulky group at the 5-hydroxymethyl produced the α-isomer as a major product. During glycosylation, the α-methyl group directed the formation of nucleosides in favor of the β-isomer. This methodology is applied to the synthesis of some new pyrimidine and purine nucleosides.
