Two convergent approaches towards the synthesis of carbocyclic nucleoside analogs will be described. Both approaches start from the stereochemically pure cyclopentenol 8 that has been prepared enantioselectively from an alkylated cyclopentadiene. Using these approaches, carbocyclic analogues of dT, FdU and BVdU have been prepared. Moreover, the conversion into the cycloSal-pronucleotide and the corresponding nucleotide will be presented for one example.
将描述两种趋同的方法用于合成碳环核苷类似物。这两种方法均以从烷基化环戊二烯中选择性制备的立体化学纯环戊醇8为起点。通过这些方法,已合成出dT、FdU和BVdU的碳环类似物。此外,还将展示一种例子中转化为环Sal-前核苷酸及相应核苷酸的过程。
