Cyclopropane derivatives and method of preparing the same

摘要

A cyclopropane derivative represented by formula (I): <IMAGE> (I) wherein B represents a group of a purine derivative. In addition another aspect of the invention provides (3-oxa-2-oxobicyclo[3,1,0]hexan-1-yl)methanol and a method of preparing a cyclopropane derivative of formula (I) from this compound by replacing the hydroxyl group of the compound with a leaving group followed by reaction with a purine derivative.
