Starting from methyl 3,5-di-O-benzyl-2-keto-alpha-D-ribofuranoside, a convergent, six-step synthesis is developed to give efficiently all four 2'-C-alpha-aminomethyl-2'-deoxynucleosides (U, C, A, G) in 38%, 42%, 12%, 12% yield, respectively. Convergence is achieved by the glycosylation of persilylated nucleobases with methyl 2-alpha-phthalimidomethyl ribofuranoside.
从甲基3,5-二-O-苄基-2-酮基的α-d呋喃核糖苷,会聚开始,六步合成进行显影,得到有效地所有四个2'-C-α-氨基甲基-2'-脱氧核苷(U,C,A,G)在38%,42%,分别为12%,产率12%。收敛通过全硅烷化的核碱基的糖基化与甲基2-α-苯二甲酰呋喃核糖苷实现。
