2'-O-Tetrahydrofuranyl nucleosides were prepared by an improved procedure via 3', 5'-tetraisopropyldisiloxanylnucleosides. A large scale synthesis of the anticodon heptanucleotide C-U-C-A-U-A-A of E. coli formylmethionine tRNA was performed by the phosphotriester method involving condensation of oligonucleotides having 2'-O-tetrahydrofuranyl protecting groups.
通过改进的3',5'-四异丙基二
硅氧烷基核苷路线,制备了2'-O-
四氢呋喃基核苷。采用
磷酰三酯法,涉及具有2'-O-
四氢呋喃保护基团的寡核苷酸的缩合反应,进行了大肠杆菌甲酰甲
硫氨酰tRNA的反密码子七核苷酸C-U-C-A-U-A-A的大规模合成。
