実験手順

A mixture of (1R,3S,4S)-3-methoxy-4-(nitrooxy)cyclopentanecarboxylic acid (example 1, 105 mg, 0.510 mmol) and benzenesulfonamide (173 mg, 1.10 mmol) was dissolved in dichloromethane (4 mL). Triethylamine (240 pl, 1.72 mmol) was added, followed by O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (291 mg, 0.765 mmol). The reaction mixture was stirred for 12 hours. Purification of the crude product by reversed-phase mass-directed high-performance liquid chromatography afforded the title compound as a white solid. 1H NMR (500 MHz, CDCl3) δ 1.93-2.02 (m, 1H), 2.15-2.26 (m, 2 H), 2.34 (dt, J=6.8, 15.7 Hz, 1H), 2.93-3.01 (m, 1H), 3.50 (s, 3H), 3.90-3.94 (m, 1H), 5.33-5.37 (m, 1H), 7.55 (t, J=7.8 Hz, 2H), 7.65 (t,J=7.5 Hz, 1H), 8.03-8.07 (m, 2H), 9.42 (s, 1H).
