| titleOfInvention | The preparation method of 6 α-amide group penicillanic acid sulfoxide compound |
| abstract | The invention discloses the preparation method of a kind of medical material 6 α-amide group penicillanic acid sulfoxide compound.In existing method, raw material BSA and DBN is expensive, buying difficulty, and reaction yield is low, and by product is many, separation difficulty, causes product content low.The preparation method of α of the present invention-amide group penicillanic acid sulfoxide compound, it is characterized in that 6 β-amide group penicillanic acid sulfoxide compound and trimethylchlorosilane react under the existence of organic bases and solvent, reaction terminates rear de-trimethyl silicane, obtains 6 α-amide group penicillanic acid sulfoxide compound.Raw material of the present invention is inexpensive, be easy to get, security is good, reduces production cost and environmental protection; The gentle easily control of reaction conditions, yield is high, is separated easily, obtains highly purified 6 α-amide group penicillanic acid sulfoxide compound. |
