- cuprous dimethyl sulfide complex (227 mg, 1.1 mmo 1) was added and the mixture was stirred for 15 minutes, and then dissolved in tetrahydrofuran (5 ml) (3S, 4R) —3 -— [(R )-1- (tert-Butyldimethylsilyloxy) ethyl] 1- 4-phenylthio-2-azetidinone (169mg, 0.5mmo1) was added and stirred for 15 minutes. A saturated ammonium chloride solution was added to the reaction product to remove insolubles, followed by extraction with ethyl acetate. The ethyl acetate calendar was washed three times with saturated saline.
- cuprous halo dimethyl sulfide complex (227 mg, 1.1 mmo 1) was added and stirred for 15 minutes, and then dissolved in tetrahydrofuran (5 ml) (3S, 4R) — 3— [(R) -1- (tert-Butyldimethylsilyloxy) ethyl-1-4-phenylthio-12-azetidinone (169 mg, 0.5 mmol) was added and stirred for 15 minutes. A saturated ammonium chloride solution was added to the reaction product to remove insolubles, followed by extraction with ethyl acetate. The ethyl acetate was washed three times with saturated saline.
- the four-replacement group of the azetidinone derivative of the general formula [1] is converted in one step to obtain a derivative of the general formula [3], and the general formulas [3] and [4]
- the derivative of [1] forms a single-arm [5] azetidinone derivative by a decarboxylation reaction. Therefore, the azetidinone derivative of the general formula [5] can be easily synthesized in a shorter step than the conventional method.
