The synthesis of 2′-deoxypseudouridine (2) is reported by condensation of 2,4-di-t-butoxy-5-lithiopyrimidine with 3,5-di-O-benzyl-2-deoxyribose and with 3,4-O-isopropylidene-2-deoxyribose (both giving the α-anomer also), and stereospecifically from pseudouridine (1)via a 4,2′-anhydro-intermediate and the 2′-chloro-2′-deoxynucleoside (4).
据报道,通过2,4-二叔丁氧基-5-硫代嘧啶与3,5-二-O-苄基-2-脱氧核糖和3,4- O-的缩合反应合成了2'-脱氧伪神经杜里啶(2)。异丙基-2-脱氧核糖(二者给予α端基异构体也)和立体有择地从假尿苷(1)通过一个4,2'-脱水中间体和2'-氯-2'-脱氧核苷(4)。
