Synthesis of spacered cyclopropyl nucleoside analogues as potential antiviral agents
摘要:
Novel spacered cyclopropane nucleoside analogues possessing both a hydroxyethyl group and an additional methylene spacer between the base and the ring were synthesized starting from 3-buten-1-ol. After tetrahydropyranylation, cyclopropanation, and reduction the target molecules were obtained by Mitsunobu reactions followed by two consecutive deprotection steps. (C) 1999 Elsevier Science Ltd.
