Novel spacered cyclopropane nucleoside analogues possessing both a hydroxye
thyl 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 Mits
unobu reactions followed by two consecutive deprotection steps. (C) 1999 El
