of cyclopropyl carbocyclic nucleosides are described. The target products have been synthesized from suitable cyclopropane precursors obtained, in turn, from olefinic compounds derived from D-glyceraldehyde as a chiral precursor. Selective manipulation of the functional groups has allowed the preparation of enantiopure nucleosides, some of them displaying opposite chirality. All these molecules contain
描述了新型的环丙基碳环核苷的多功能和立体控制合成词条。已经从合适的环丙烷前体合成了目标产物,所述合适的环丙烷前体又从作为手性前体的D-甘油醛衍生的烯烃化合物获得。官能团的选择性操作允许制备对映体纯的核苷,其中一些显示相反的手性。所有这些分子在环丙烷环的C-1或C-3处含有一个立体立体碳,并带有一个氨基,羟甲基或甲基作为附加取代基。在一种情况下,胸腺嘧啶直接与环丙烷连接。亚甲基单元用作其他合成核苷中的间隔基。
