实验步骤: To a vigorous stirring solution of tert-butyl (4-oxocyclohexyl)methylcarbamate (1.7 g) in tetrahydrofuran (40 mL) at −78° C. was dropwise added 1.6 M methyllithium (14.02 mL) in ether. After completion of the addition, the mixture was stirred at −78° C. for 1.2 hours and poured into a cold aqueous NH4Cl solution. The resulting mixture was extracted with dichloromethane (3×100 mL) and the organic layer was dried over Na2SO4, filtered and concentrated. The residue was dissolved in dichloromethane and loaded onto an Analogix purification system, eluted with 0-50% ethyl acetate in dichloromethane to provide the title compound. at −78° C. After completion of the addition The resulting mixture was extracted with dichloromethane (3×100 mL) the organic layer was dried over Na2SO4 filtered concentrated The residue was dissolved in dichloromethane loaded onto an Analogix purification system eluted with 0-50% ethyl acetate in dichloromethane

实验步骤: A solution of tert-butyl (4-oxocyclohexyl)methylcarbamate (1.00 g) was dissolved in tetrahydrofuran (20 mL) and cooled to −78° C. Methylmagnesium bromide (4.40 mL) was added dropwise. The reaction was stirred for 2 hours at −78° C. then allowed to warm to 0° C. and stirred for 30 minutes. The resulting suspension was quenched with water (10 mL), diluted with ether (50 mL), washed with ammonium chloride (25 mL), washed with brine (25 mL), dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography (Reveleris 80 g) eluting using a gradient of 5% to 50% ethyl acetate/dichloromethane over 30 minutes (flow=60 mL/min) gave the title compound as a ˜2:1 mixture of cis and trans isomers. to warm to 0° C. stirred for 30 minutes The resulting suspension was quenched with water (10 mL) diluted with ether (50 mL) washed with ammonium chloride (25 mL) washed with brine (25 mL) dried over magnesium sulfate filtered concentrated Silica gel chromatography (Reveleris 80 g) eluting over 30 minutes

After completion of the addition, the mixture was stirred at −78° C. for 1.2 hours and poured into a cold NH4Cl aqueous solution. The resulting mixture was extracted with dichloromethane (100 ml, three times) and the organic layer was dried over Na2SO4, filtered, and concentrated. The residue was dissolved in dichloromethane and loaded onto an Analogix purification system, and it was eluted with 0-50% ethyl acetate in dichloromethane to provide the title compound. at −78° C.
