| titleOfInvention | The preparation method of 7 β-amide group-7 α-methoxyl group-1-oxo-3-cephem compounds |
| abstract | The present invention relates to the preparation method of a kind of medical material 7 β-amide group-7 α-methoxyl group-1-oxo-3-cephem compounds.In existing method, mostly there is the problem that step is many, yield is low.The preparation method of the present invention 7 β-amide group-7 α-methoxyl group-1-oxo-3-cephem compounds, it is characterized in that using 'beta '-lactam compounds and TCCA (Trichloroisocyanuric acid) to react, generate N-chloroamides base-'beta '-lactam compounds, add organic bases dechlorination, generate N-alkenyl amide base-'beta '-lactam compounds, N-alkenyl amide base-'beta '-lactam compounds and methyl alcohol addition generate 7 β-amide group-7 α-methoxyl group-1-oxo-3-cephem compounds.The gentle easily control of reaction conditions of the present invention, yield is high, obtains highly purified 7 β-amide group-7 α-methoxyl group-1-oxo-3-cephem compounds product. |
