  Cefiderocol (S-649266), A new siderophore cephalosporin exhibiting potent activities against Pseudomonas aeruginosa and other gram-negative pathogens including multi-drug resistant bacteria: Structure activity relationship

  摘要：

  The structure-activity relationship (SAR) for a novel series of catechol conjugated siderophore cephalosporins is described with their in vitro activities against multi-drug resistant Gram-negative pathogens including Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Enterobacteriaceae. Cefiderocol (3) was one of the best molecules which displayed well-balanced and potent activities against multi-drug resistant Gram-negative pathogens including carbapenem resistant bacteria among the prepared compounds with the modified C-7 side chain and the modified C-3 side chain. Cefiderocol (3) is a highly promising parenteral cephalosporin for the treatment of multi-drug resistant Gram-negative infection. (C) 2018 Elsevier Masson SAS. All rights reserved.

  光氧化还原与镍催化相结合的富电子烯烃的三组分氨基芳基化

  摘要：

  报道了通过协同光氧化还原和镍催化对乙烯基醚、烯酰胺、烯-氨基甲酸酯和乙烯基硫醚进行三组分 1,2-氨基芳基化。 2,2,2-三氟乙氧基羰基保护的α-氨基含氧酸用作酰胺基自由基前体。酰胺自由基与烯烃的反马可夫尼科夫加成和 Ni 介导的自由基/过渡金属交叉导致相应的 1,2-氨基芳基化产物。自由基级联反应可以在实际且温和的条件下进行，具有高官能团耐受性和广泛的底物范围。使用L-(+)-乳酸衍生的乙烯基醚作为底物实现立体选择性1,2-氨基芳基化，为制备受保护的对映体纯α-芳基化β-氨基醇提供了新的途径。此外，乙烯基醚的1,2-氨基酰化是通过使用酰基琥珀酰亚胺作为Ni介导的自由基偶联的亲电子试剂来实现的。
