Nucleosides and nucleotides. 232. Synthesis of 2′-C-methyl-4′- thiocytidine: Unexpected anomerization of the 2′-keto-4′- thionucleoside precursor

□ The synthesis of 2′-C-methyl-4′-thiocytidine (16) is described. Since the 2′-keto-4′-thiocytidine derivative 2β unexpectedly isomerized to 2α and the methylation of 2β proceeded predominantly from the less hindered α-face to give 7, the desired product
