  描述：

  Benzo[b]thiophen-5-yl-tert-butoxycarbonylamino-acetic acid 在 碳酸氢钠 、 对甲苯磺酸 、 2-乙氧基-1-乙氧碳酰基-1,2-二氢喹啉 作用下， 以 四氢呋喃 、 乙腈 为溶剂， 反应 6.0h， 生成 (6R,7R)-7-((R)-2-Amino-2-benzo[b]thiophen-5-yl-acetylamino)-3-methyl-8-oxo-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylic acid 4-nitro-benzyl ester

  Orally absorbable cephalosporin antibiotics. 2. Structure-activity studies of bicyclic glycine derivatives of 7-aminodeacetoxycephalosporanic acid

  摘要：

  Three positional analogues (4-, 5-, and 7-) of benzothienylglycine and (N-acetylindolinyl)-5-glycine were prepared and coupled to 7-aminodeacetoxycephalosporanic acid (7-ADCA) to give the cephalosporins 17a-c. In addition two isomeric (2,3-b and 3,2-b) thienothiopheneglycines were synthesized and coupled to 7-ADCA to yield cephalosporins 30d and 30e. In vitro testing of these new cephalosporins indicates good activity against Gram-positive bacteria. Against Streptococcus pneumoniae infections compound 25 displayed better mouse protection (both orally and subcutaneously) than cephalexin.
