variety of meaningful biological properties. Derivatives of these compounds possessing substituents at the hydroxyl and heterocyclic ring bearing carbon atoms have not been described. As entries into these compounds, the 4'- and 1'-methyl derivatives of 5'-noraristeromycin (2 and 3) have been prepared from a common cyclopentyl precursor 8. The synthetic methods developed are adaptable to 5'-norcarbanucleosides
已经发现5'-降碳环核苷具有多种有意义的生物学特性。这些化合物在羟基和带有杂环的碳原子上具有取代基的衍生物尚未被描述。作为这些化合物的入口,已经从常见的环戊基前体8制备了5'-去甲紫红霉素(2和3)的4'-和1'-甲基衍生物。开发的合成方法适用于具有多种形式的5'-去甲碳核苷。杂环碱基的构型,并呈l样构型。反过来,这些合成的产物将有助于进行与碳核苷有关的大量结构和生化研究。化合物2和3缺乏抗病毒特性,并且没有细胞毒性。
