94% | With methanol; sodium methylate; at 20℃; | 2. Synthesis of 1-O-(p-Methoxy phenyl)-beta-D-glucopyranoside; II (RSCL-0369) To a stirred solution of compound I (12 g, 24.2 mmol) in methanol (25 mL) was gradually added 2 mL of a 25% (w/v) sodium methoxide/methanol solution. The resulting solution was stirred at room temperature overnight. The mixture was neutralized by Amberlyst 15 ion-exchange (H+) resin. The neutralized reaction mixture was filtered, concentrated and purified using silica gel column chromatography (20% methanol/dichloromethane). The organic fractions containing desired product were concentrated and dried under high vacuum (2 mm/Hg) to provide viscous compound II (yield 6.5 g, 94%); Rf 0.55 (10% methanol/dichloromethane); 1H NMR (CD3OD) delta 3.77 (s, 3H), 4.06 (dd, 1H, J=12 Hz), 4.27 (dd, 1H, J=5.1 Hz), 4.52 (d, 1H, J=7.2 Hz), 6.81 (d, 1H), 6.94 (2d, 1H); MS m/z 309 (M+Na)+.

The solution wasstirred 1 h and followed by TLC (30:70; EtOAc : hexanes). A solution of NaHCO3(aq) wasadded and the mixture was extracted with DCM, washed with brine, dried over Na2SO4,filtered and concentrated in vacuo. The alpha/beta ratio was measured by 1H NMR on the crude.The residue was treated with a freshly prepared solution MeONa (0.25 equiv., 0.5 M inmethanol) in dry methanol (0.3 M). The solution was stirred at r.t. for 1 h andneutralized with Amberlite IR-120 H+, filtered and concentrated in vacuo to give a whitesolid. Quick flash column chromatography (10:90; MeOH:DCM) removed excess of ArOHand led to the beta-D anomer, which was recrystallized in hot ethanol. 4-Methoxyphenyl-alpha-D-glucopyranoside (24)White solid (50 mg, 82%, 1:>20, alpha:beta).Melting point : 170C (lit. 175-177C)3[alpha]D25 -58.9 (c 0.05, MeOH)IR (neat) numax 3358, 3026, 2921, 1645, 1508, 1219, 1072 cm-11H NMR (500 MHz, CD3OD): delta = 7.05 (d, J = 9.1 Hz, 2H), 6.83 (d, J = 9.1 Hz, 2H), 4.77 (d, J= 7.5 Hz, 1H, H-1), 3.88 (dd, J = 8.8, 3.4 Hz, 1H, H-4), 3.75 (s, 3H), 3.72 - 3.65 (m, 1H, H-3), 3.48 - 3.36 (m, 4H, H-2, H-5, 2H-6).13C NMR (125 MHz, CD3OD): delta = 156.7, 153.2, 119.2, 115.4, 103.5, 78.1, 78.0, 75.0, 71.4,62.6, 56.0.HRMS: m/z [ESI] calcd for C13H18O7Na (M+Na)+ : 309.0945, found: 309.0954 (+3.03ppm). |
