    • 3 (950 mg, 3.6 mmol, 1.5 equiv) in fresly distilled THF (50 mL) kept under Ar atmosphere at 0 °C. The mixture was stirred for 30 min and then the purine base was added (3.6 mmol, 1.5 equiv). The mixture was stirred for an additional 30 min and then a solution of epoxide 7 (450 mg, 2.4 mmol, 1 equiv) in dry THF (5 mL) was added slowly. The cooling bath was removed and the mixture allowed to warm to r.t. The mixture was stirred for 12 h at r.t.(chloropurine) or 12 h at r.t. then 4 h at 40 °C (adenine, 2-aminochloropurine). The solvent was removed under reduced pressure and the residue was chromatographed on a silica gel column (gradients hexane-EtOAc as eluent). Compounds 8 (66% yield) and 9 (56% yield) were obtained pure as white solids, but 10 was contaminated with inseparable triphenylphosphine oxide.
