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.
本文介绍了合成 2'-脱氧-6,2'-甲尿苷(1)、-胞苷(3)和-4-硫尿苷(13)的另一种方法,该方法涉及异丙基 β-D-2-pentuloside (5)和由 6-三甲基硅甲基嘧啶(6)形成的碳离子的缩合,然后进行分子内糖基化。
