analogue of thymidine monophosphate and its association towards the formation of a new borono-linked dinucleotide. Here we describe the completion of the set of four 2′-deoxyborononucleotide analogues of natural nucleotide monophosphates, namely the previously unknown dCbn, dGbn and dAbn. These analogues were all prepared from the respective 5′-aldehydic nucleosides through a homologation/reduction sequence
我们之前曾报道过 胸苷一磷酸及其与形成新的与硼烷连接的二核苷酸的联系。在这里我们描述了这四个集合的完成2'-脱氧硼核苷酸 天然核苷酸单磷酸酯的类似物,即以前未知的dCbn, dGbn和dAbn。这些类似物均通过相应的同源/还原序列由各自的5'-醛核苷制备。随后通过硼酸化(dCbn和dGbn)或在Hoveyda-Grubbs催化剂(dAbn)存在下进行交叉复分解(CM)。这些新类似物与尿苷通过1 H NMR研究,并进行了半经验计算,以提供键长和静电信息,以评估这些生物等排体及其天然对等体之间存在的结构相似性。
