An alternative method for the synthesis of 2'-deoxy-6, 2'-methanouridine (1), -cytidine (3) and -4-thiouridine (13) is described which involves a condensation of an isopropyl β-D-2-pentuloside (5) and a carbanion formed from 6-trimethylsilylmethylpyrimidine (6), followed by intramolecular glycosylation.
