Stereoselective Introduction of Fluorine Atom: Synthesis of Racemic Carbocyclic Analogues of 3′-Deoxy-3′-fluororibofuranosides and 3′-Deoxy-3′-fluoroarabinofuranosides
Newcarbocyclicanalogues of nucleoside analogues substituted at the 3′-position with fluorine atom have been synthesized. Racemic carbocyclic3′-deoxy-3′-fluoroarabinofuranoside analogue (3) has been prepared in several steps beginning with the regio- and stereoselective ring opening of (1α,2α,3α,4α)-4-acetamido-2,3-epoxycyclopentylmethylacetate (1). On the other hand, the corresponding carbocyclic
