An improved procedure for the preparation of a versatile synthetic precursor, (+)-13, of carba-2'-deoxyribonucleosides and the first stereospecific way to enantiomerically pure carbocyclic 2'-deoxyadenosine, (+)-14, are presented from bicyclic lactone diol (+)-1. An unexpected formation of the disubstituted 2-oxabicyclo[2.2.1]heptane skeleton 15 through a hypervalent iodo species derived from 6 is also reported.
