실험 절차

A solution of 20 (186 mg, 0.906 mmol), 1 (153 mg, 0.955 mmol), and acetic acid (288 mg, 4.80 mmol) in methanol (1 mL) was treated with sodium cyanoborohydride (63 mg, 1.00 mmol) at room temperature. The resulting mixture was stirred at room temperature (2 h). The solvent was removed in vacuo and the residue dissolved in dichloromethane and sodium bicarbonate solution. The aqueous layer was extracted with two additional portions of dichloromethane and the combined organic extracts were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. PCTLC (SiO2, 2 mm, 10% EtOH; 90% CHCl3) afforded the title compound (21).
