実験手順
4-[4-(3-Pyrrolidin-1-ylpropoxy)phenyl]tetrahydro-2H-pyran-4-carbaldehyde (350 mg, 1.103 mmol), (s)-(+)-2-(methoxymethyl)pyrrolidine (230 mg, 2.00 mmol), absolute ethanol (40 ml), activated 3 Å molecular sieves (350 mg), titanium (IV) isopropoxide (1.62 ml, 5.48 mmol) and STAB (2.09, 9.74 mmol) were reacted in accordance with the general procedure D. The isolated crude product was purified by column chromatography on silica eluting with DCM:MeOH:NH3 (98:1:1) to give the title compound as a white solid (330 mg, 72%). 1H NMR (400 MHz, CDCl3) δ7.18 (d, 2H), 6.86 (d, 2H), 4.02 (t, 2H), 3.84-3.70 (m, 2H), 3.59 (td, 1H), 3.45 (td, 1H), 3.27 (s, 3H), 3.10 (dd, 1H), 3.02 (dd, 1H), 2.94 (d, 1H), 2.63 (t, 2H), 2.59-2.45 (m, 5H), 2.39 (m, 1H), 2.21 (m, 1H), 2.06-1.34 (m, 15H).
