  描述：

  methyl 2-keto-2-(thieno[2,3-b]thiophen-2-yl)thioacetate 在 sodium hydroxide 、 草酰氯 、 N,O-双(三甲基硅烷基)三氟乙酰胺 作用下， 以 甲醇 、 N,N-二甲基甲酰胺 、 乙腈 为溶剂， 反应 3.5h， 生成 (6R,7R)-7-{2-[(Z)-Methoxyimino]-2-thieno[2,3-b]thiophen-2-yl-acetylamino}-3-methyl-8-oxo-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylic acid

  名称：

  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.
