摘 要:以7-氨基頭孢烷酸為原料,于綠色溶媒碳酸二甲酯反應溶劑中,以三氟化硼/碳酸二甲酯絡(luò )合物為催化劑,與5-甲基四氮唑反應合成了中間體7-氨基-3-[2-(5-甲基-2H-四氮唑基)甲基]頭孢烷酸,然后與2-(2-氨基-4-噻唑基)-2-(甲氧亞氨基)乙酸硫代苯并噻唑酯反應合成了頭孢特侖酸。優(yōu)化條件下頭孢特侖酸純度98.8%,總收率63.8%。該合成工藝具有反應周期短、收率和純度高、操作簡(jiǎn)單等優(yōu)點(diǎn),適合工業(yè)化生產(chǎn)。 |

Abstract:Cefteram acid was obtained from the reaction of 7-ACA and 5-methyl-1H-tetrazol with 2-(2-Amino-4-thiazolyl)-2-methoxyiminoacetic thiobenzothiazole ester using boron trifluoride/dimethyl carbonate complex as the catalyst. Under the optimizing condition, the purity of cefteram acid reached 98.8% , and the overall yield was 63.8%. This synthetic process was proved to be with many advantages including high yield, high purity, and simple-processing; it was suitable for industrial production. |
Key words:Cefteram acid; 7-ACA; 5-methyl-1H-tertazole |
