実験手順

Diethyl azodicarboxylate (158 mL) was added to a mixture of (2S,4R)-4-(N-tert-butoxycarbonylglycylamino)-2-hydroxymethyl-N-tert-butoxycarbonylpyrrolidine (A, 310 mg), 4-phenylphenol (148 mg), and triphenyl phosphine (229 mg) in tetrahydrofuran (10 mL) under argon at room temperature. After stirring at room Ad temperature for 17 hr, the mixture was concentrated in vacuo to give a residue, which was purified by silica gel column chromatography (chloroform:methanol=200:1, v/v) to afford title compound (431 mg): 1H NMR (400 MHz, CDCl3) δ 1.44 (s, 18H), 2.01 (m, 1H), 2.38 (m, 1H), 3.21 (m, 1H), 3.72 (m, 1H), 3.77 (d, J=4.4 Hz, 2H), 3.99-4.25 (m, 3H), 4.68 (m, 1H), 5.49 (m, 1H), 6.85 (m, 1H), 6.97 (d, J=7.3 Hz, 2H), 7.29 (d, J=7.3 Hz, 1H), 7.40 (t, J=7.3 Hz, 2H), 7.48-7.63 (m, 4H).
