  (6S,8R)-8-t-butyldimethylsilyloxy-3,3-dimethyl-2-oxo-1-aza-4-oxabicyclo[4.3.0]nonane 在 盐酸 、 sodium hydroxide 、 氨 、 sodium methylate 、 sodium hydride 、 三乙胺 、 N,N-二异丙基乙胺 作用下， 以 四氢呋喃 、 甲醇 、 乙醇 、 水 、 乙腈 为溶剂， 反应 16.0h， 生成 (4-nitrophenyl)methyl (4R,5S,6S)-3-[(3S,5S)-5-[(1-amino-2-methyl-1-oxopropan-2-yl)oxymethyl]-1-[(4-nitrophenyl)methoxycarbonyl]pyrrolidin-3-yl]sulfanyl-6-[(1R)-1-hydroxyethyl]-4-methyl-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate

  Synthesis and antibacterial activity of novel 4-pyrrolidinylthio carbapenems—I. 2-alkoxymethyl derivatives

  摘要：

  The synthesis and in vitro antibacterial activity of a novel series of 2-alkoxymethyl-4-pyrrolidinylthio-1 beta-methyl carbapenems are described. As a result of these studies, we discovered that FR27743 (19j) containing a novel,2-fluoroethoxymethyl substituent possesses a broad spectrum of antibacterial activity against both Gram-positive and Gram-negative organisms, including Pseudomonas aeruginosa. Furthermore, FR27743 exhibited excellent stability against renal dehydropeptidase-I (DHP-I), good urinary recovery, and superior in vivo activity compared to that for Meropenem against several systemic infections.
