Procedure
To a stirred suspension of 1-11 (530 mg, 1.41 mmol), 1-6(460 mg, 1.41 mmol) and triethylamine (0.59 mL, 4.24 mmol) in 1,2-dichloroethane (15 mL) was added sodium triacetoxyborohydride (449 mg, 2.12 mmol) and the mixture was stirred for 16 h. The reaction mixture was diluted with ethyl acetate and washed with saturated aqueous sodium hydrogen carbonate, saturated aqueous sodium chloride, and dried over anhydrous magnesium sulfate. The reaction mixture was filtered and concentrated at reduced pressure. The resulting oil was purified by flash column chromatography (silica gel, 3:0.3:0.3 to 8:0.8:0.8% ethanol/ammonium hydroxide/water in ethyl acetate) to give 1-12 as an inseparable mixture of diastereomers.
