实验步骤: To a stirred mixture of 3-hydroxycyclobutyl pivalate (16.60 g, 96.4 mmol) and diea (25.2 ml, 145 mmol) in DCM (100 ml) at 0° C. was added tert-butyldimethylsilyl triflate (31.0 ml, 135 mmol) dropwise. The reaction was stirred for 2 h, then quenched with H2O. The layers were separated, and the organic layer was washed with saturated NaHCO3, brine, dried over MgSO4 and concentrated to give the title compound as a light brown oil. quenched with H2O The layers were separated the organic layer was washed with saturated NaHCO3, brine dried over MgSO4 concentrated

实验步骤: To a stirred solution of 3-oxocyclobutyl pivalate (15.1 g, 88.7 mmol) in ethanol (100 ml) at 0° C. was added sodium borohydride (4.69 ml, 133 mmol) in several portions. The reaction was stirred for 30 min, slowly quenched with 10% aqueous HCl and concentrated to remove ethanol. The solution was taken up with more 10% HCl, extracted with DCM (3×), washed with brine, dried over MgSO4 and concentrated to give the title compound as a light yellow oil. slowly quenched with 10% aqueous HCl concentrated to remove ethanol extracted with DCM (3×) washed with brine dried over MgSO4 concentrated
