実験手順

CuI (0.35 mg, 0.002 mmol) and phenylacetylene (2.1 mmol) were added to a solution of (4S,2R,3R,5R)-5-(hydroxymethyl)-2-[2-iodo-6-(methoxyamino)purin-9-yl]oxolane-3,4-diol (0.35 mmol), a compound of formula (5), in dry N,N-dimethylformamide (6 mL) and triethylamine (1.4 mL) under an atmosphere of nitrogen in the presence of bis(triphenylphosphine)palladium dichloride (5 mg, 0.007 mmol). The reaction mixture was stirred at room temperature for 5 hours. After evaporation under reduced pressure the residual oil was purified by silica gel column chromatography, eluting with chloroform/methanol 90/10. After evaporation in vacuo, the residual oil was purified by silica gel column chromatography, eluting with the suitable mixture of solvents, to provide (4S,2R,3R,5R)-5-(hydroxymethyl)-2-[6-(methoxyamino)-2-(2-phenylethynyl)purin-9-yl]oxolane-3,4-diol, a compound of Formula I (mp 175-177° C.).
