| titleOfInvention | Stereoselective preparation of 4-acetoxyazetidinone derivatives |
| abstract | The 4-carboxyzecidinone N-substituent of Structural Formula (I) was electrochemically reacted by applying a direct current to an electrode in the presence of an electrolyte selected from the group consisting of alkali metal salts and amine bases of acetic acid in a mixed solvent of acetic acid and an organic solvent. Then, a method of stereoselectively synthesizing 4-acetoxyazetidinone of formula (II) by one-way reaction by adding only an appropriate amount of water without separating the reaction product and then flowing a direct current under the same conditions to deprotect the aryl group Is provided.n n n n n n n n Wherein R 1 represents a trialkylsilyl group; R 2 represents an aryl group.n n n According to the production method of the present invention, 4-acetoxyazetidinone is obtained in one-way reaction by electrochemical reaction, thus overcoming the problem of environmental stigma with cost reduction; The advantages of easy industrialization, simple manufacturing process and high yield are provided. |
