実験手順

To a mixture of 9-hydroxy-6-phthalimidopurine (320 mg, 1.14 mmol) , diethyl (Z)-4-hydroxybut-1-enylphosphonate (250 mg, 1.20 mmol) and triphenyl phosphine (448 mg, 1.71 mmol) in dry tetrahydrofuran (11 ml) stirred at 0° C. under dry nitrogen was added diethyl azodicarboxylate (296 mg, 170 mmol). The mixture was allowed to warm to r.t. and stirred for 2.3 hr. The solvent was removed and the residue was purified by column chromatography on silica gel eluting with acetone-hexane (1:1, 4:3) to give (Z)-9-[4-(diethoxyphosphoryl)but-3-enyloxy]-6-phthalimidopurine as a light brown gum (320 mg, 60%); λmax (EtOH) 271 (14,680)nm; υmax (KBr) 2980, 1735, 1595, 1575, 1360, 1330, 1245 and 1025 cm-1 ; δH [(CD3)2SO] 1.23 (6H, t, J 7 Hz, CH3), 3.05 (2H, m, CH2), 3.98 (4H, dq, J 7 Hz and 8Hz, CH2CH 3), 4.63 (2H, t, J 6 Hz, CH2O ), 5.90 (1H, dd, J 14 Hz and 20 Hz, PCH=CH), 6.75 (1H, ddt, J 7 Hz, 14 Hz and 52 Hz, PCH=CH), 8.05 (4H, m, C6H4), 9.05 (1H, s, H-2/H-8), 9.10 (1H, s, H-2/H-8) (Found: C, 53.77; H, 4.87; N, 14.52%; MH+ 472.1384. C21H22N5O6P requires C, 53.50; H, 4.70; N, 14.86%; MH+ 472.1386).
