  Synthesis and antibacterial activities of novel C(3)-aminopyrimidinyl substituted cephalosporins including against respiratory tract pathogens

  摘要：

  The variety of cephalosporins 1 and 2 which possessed C(3)-aminopyrimidinyl substituents were prepared and evaluated for their antibacterial activities. They exhibited excellent in vitro activities especially against respiratory tract pathogens such as penicillin resistant Streptococus pneumonia, Moraxella catarrhalis and Haemophilus influenza.

  A practical synthesis of triethylammonium (Z)-2-[2-(N-tert-butoxycarbonylamino)thiazol-4-yl]-2-(triphenylmethyloxyimino)acetate (1) which is the C-7 side chain of cefmatilen, a new cephalosporin antibiotic, is described. The conditions were optimized to control the impurity and to increase the yield. Selective acetylation of oxime group before tert-butoxycarbonylation reduced the amount of Boc2O. Compound

  三乙基铵的实用合成（ż）-2- [2-（Ñ -叔丁氧羰基）噻唑-4-基] -2-（triphenylmethyloxyimino）乙酸甲酯（1），这是cefmatilen的C-7侧链，一个新的描述了头孢菌素抗生素。优化条件以控制杂质并提高产率。叔丁氧基羰基化之前肟基团的选择性乙酰化减少了Boc 2 O的量。通过这种改进的方法，由化合物6合成的化合物1的总产率为80％（比药用过程的产率高12％），并通过四反应序列进行合成。 （每个反应95％）。
