Abstract
A convenient synthesis of racemic 2'-deoxy carbocyclic thymidines lack ing the 5'-methylene group is reported. Thus, appropriately protected nucleic acid bases are coupled to 3-cyclopentenol, 1, via the Mitsunob u reaction. Epoxidation of the protected thymine substituted cyclopent ene gives the corresponding syn and anti-epoxides in a 4:1 ratio. Ring opening of the syn-epoxide by a variety of nucleophiles leads to the racemic 2'-deoxy carbocyclic thymidines lacking the 5'-methylene group . (C) 1998 Elsevier Science Ltd. All rights reserved.
