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

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a stirred suspension of zinc dust (103 g, 1568 mmol) in HOAc (200 ml) was added a solution of 2,2-dichloro-3-oxocyclobutyl pivalate (75 g, 314 mmol) in HOAc (400 ml) dropwise in an ice bath. The reaction mixture was stirred for 1 h, filtered the solid through celite and washed with DCM. The DCM layer was washed with H2O, NaHCO3, brine, dried over MgSO4, filtered and concentrated. The crude material was purified by ISCO (10% EtOAc/Hexanes) to give the title compound as a light yellow oil. filtered the solid through celite washed with DCM The DCM layer was washed with H2O, NaHCO3, brine dried over MgSO4 filtered concentrated The crude material was purified by ISCO (10% EtOAc/Hexanes)
