  Synthesis of Imidazole C1- and C3-Ribonucleoside Phosphoramidites for Probing Catalytic Mechanism in Ribozyme

  摘要：

  Synthesis of C4-linked imidazole N-pivaloyloxymethyl (P0M)-2'-O-cyanoethylated (CE) C-1- and C-3-ribonucleoside phosphoramidites 1a and 1b is described. These phosphoramidite products were incorporated into RNA sequence through solid phase phosphoramidite approach, providing RNA with imidazole linked through different length to sugar residue, to study the mechanism of a ribozyme.

  Synthesis of (+)-Pericosine B, (+)-Pericosine C, (+)-COTC and a 7-chloro-analogue of (+)-Gabosine C was achieved via tandem seleno-Michael/aldol reactions as key steps. The carbasugar linear precursor was obtained from cheap and readily available d-ribose in 7 steps which included resolution of the d-ribopyranose and the d-ribofuranose forms. Further transformation of the cyclic product involving a

  （+）-Pericosine B，（+）-Pericosine C，（+）-COTC和（+）-Gabosine C的7-氯类似物的合成是通过串联硒代-Michael / aldol反应作为关键步骤实现的。Carbasugar线性前体可通过7个步骤从廉价且容易获得的d-核糖中获得，包括拆分d-核糖吡喃糖和d-核呋喃糖形式。涉及区域选择性Steglich酯化或仲羟基甲基化的环状产物的进一步转化产生了受保护的（+）-COTC，（+）-Pericosine B和（+）-PericosineC。苄基醚在-78°脱保护C以令人满意的产率得到标题化合物。
