実験手順
Metallation of 1-bromo-3-(2-propylpentyloxy)benzene followed by addition of (R)-(−)-epichlorohydrin gave (S)-1-chloro-3-(3-(2-propylpentyloxy)phenyl)propan-2-ol Yield (1.52 g, 58%): 1H NMR (400 MHz, DMSO-d6) δ 7.14 (t, J=7.8 Hz, 1H), 6.77-6.72 (m, 3H), 5.14 (d, J=5.6 Hz, 1H), 3.88-3.81 (m, 1H), 3.78 (d, J=5.6 Hz, 2H), 3.52 (dd, J=10.8, 4.4 Hz, 1H), 3.43 (dd, J=11.2, 5.6 Hz, 1H), 2.74 (dd, J=13.6, 5.2 Hz, 1H), 2.60, (dd, J=13.6, 7.6 Hz, 1H), 1.75-1.69 (m, 1H), 1.39-1.25 (m, 8H), 0.85 (t, J=7.0 Hz, 6H).
