The approach can be applied to a wide range of differently substituted phenols including not only mono-substituted ones bearing electron-donating and electron-withdrawing groups but also disubstituted ones. Ultimately, 2,6-dideoxy aryl-O-glycosides were obtained rapidly (<30 min) in good to excellent yields (52–88%) with sole α-selectivity.

Simul. 2012; 38: 1022 22 General Procedure To a solution of the glycosyl donor 1 (41.1 mg, 0.15 mmol) in anhydrous MeCN (4 mL) was added a glycosyl acceptor phenol (0.1 mmol). After stirring for 5 min, 32.4 µL of anhydrous FeCl3 solution (0.002 mmol of FeCl3 in MeCN) were added at 0 °C. After completion (monitored by TLC), the reaction mixture was quenched with saturated aqueous NaHCO3 solution (5 mL) and extracted with CH2Cl2 (5 mL × 2). The combined organic layers were washed with brine (5 mL), dried over anhydrous Na2SO4, filtered, and concentrated under vacuum. The crude product was purified by column chromatography with petroleum ether/ethyl acetate as an eluent to obtain the corresponding glycosides. 23 Selected Spectral Data p-(tert-Butyl)phenyl 2-deoxy-3,4-di-O-acetyl rhamnopyranoside (3a) 1H NMR (500 MHz, CDCl3): δ = 7.30 (d, J = 8.7 Hz, 2 H), 7.00 (d, J = 8.7 Hz, 2 H), 5.57 (d, J = 2.1 Hz, 1 H), 5.48 (ddd, J = 11.5, 9.6, 5.4 Hz, 1 H), 4.82 (t, J = 9.6 Hz, 1 H), 3.98 (dq, J = 12.4, 6.2 Hz, 1 H), 2.42 (dd, J = 12.7, 4.9 Hz, 1 H), 2.06 (s, 3 H), 2.04 (s, 3 H), 1.94 (td, J = 12.8, 3.4 Hz, 1 H), 1.30 (s, 9 H), 1.15 (d, J = 6.2 Hz, 3 H). 13C NMR (125 MHz, CDCl3): δ = 170.50, 170.40, 154.42, 144.99, 126.40, 115.87, 95.38, 74.84, 69.06, 66.49, 35.58, 34.29, 31.63, 21.19, 20.99, 17.74.
