Highly efficient and practical methodology for the syntheses of D- and l-4,5-O-isopropylidene-2-cyclopentenone (9 and 22), versatile intermediates for the synthesis of carbocyclic nucleosides, have been developed via a ring-closing metathesis reaction from d-ribose in eight steps. The utility of D- and l-4,5-O-isopropylidene-2-cyclopentenone is demonstrated by their application for the preparation
通过闭环易位反应,开发了用于合成D-和1-4,5-O-异亚丙基-2-环戊烯酮(9和22)(合成碳环核苷的通用中间体)的高效实用方法八个步骤从d-核糖中提取。D-和1-4,5-O-异亚丙基-2-环戊烯酮在制备D-环戊基-6-氮杂嘧啶12和D-环戊烯基-5-卤代胞嘧啶核苷中的应用证明了其实用性(33-35)使用Mitsunobu反应引入嘧啶碱基作为潜在的抗病毒剂。描述了对合成核苷的正痘病毒(天花,猴痘和牛痘病毒)的初步抗病毒活性。
