  • Visible Light‐Catalyzed Decarboxylative Alkynylation of Arenediazonium Salts with Alkynyl Carboxylic Acids: Direct Access to Aryl Alkynes by Organic Photoredox Catalysis
    作者:Liangfeng Yang、Haifeng Li、Yijun Du、Kai Cheng、Chenze Qi

    日期:2019.11.5
    salts have been utilized as the aryl radical source to couple alkynyl carboxylic acids to feature the decarboxylative arylation. A wide range of substrates are amenable to this protocol with broad functional group tolerance, and diversely‐functionalized aryl alkynes could be synthesized under mild, neutral and transition metal‐free reaction conditions using visible light irradiation. Alongside synthetic
    开发了一种由光氧化还原催化介导的简便方法,用于直接构建芳基炔烃。现成的芳族重氮盐已被用作芳基自由基源,以偶联炔基羧酸以形成脱羧芳基化。各种各样的底物都适合该方案,具有宽泛的官能团耐受性,并且可以使用可见光在温和,中性和无过渡属的反应条件下合成功能多样的芳基炔烃。除了与光催化和无过渡属操作相关的合成可持续性外,该方法的另一个关键点是有机染料催化剂可作为激发态还原剂,从而建立了自由基加成和脱羧消除的淬灭循环。
  • Studies on Anti-MRSA Parenteral Cephalosporins. III. Synthesis and Antibacterial Activity of 7.BETA.-[2-(5-Amino-1,2,4-thiadiazol-3-yl)-2(Z)-alkoxyiminoacetamido]-3-[(E)-2-(1-alkylimidazo[1,2-b]pyridazinium-6-yl)thiovinyl]-3-cephem-4-carboxylates and Related Compounds.

    In the course of our exploration for a novel cephalosporin derivative having excellent antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), we modified the C-3 linked spacers of cephem derivatives bearing a l-methylimidazo[l, 2-b]pyridazinium-6-yl group at the C-3' position and 2-(5-amino-l, 2, 4-thiadiazol-3-yl)-2(Z)-cyclopentyloxyiminoacetyl group at the C-7 position. The optimal spacers were the (E)-2-vinyl and (E)-2-thiovinyl groups seen in 19a and 29aa, respectively. Their anti-MRSA activity was 16 to 32 times as potent as that of cefozopran (CZOP). Focusing on the (E)-2-vinyl and (E)-2-thiovinyl spacers, we further modified the alkoxyimino groups in the C-7 acyl moiety and the 1-alkylimidazo[l, 2-b]pyridazinium moieties at the C-3' position and investigated the structureactivity relationships (SAR) of the derivatives. Consequently, we selected 7β-[2-(5-aminol, 2, 4-thiadiazol-3-yl)-2(Z)-fluoromethoxyiminoacetamido]-3-[(E)-2-(l-methylimidazo[l, 2-b]pyridazinium-6-yl)thiovinyl]-3-cephem-4-carboxylate (29ca) as a new anti-MRSA parenteral cephalosporin candidate for further biological evaluation. The selected 29ca showed anti-MRSA activity comparable to that of vancomycin (VCM) both in vitro and in vivo, high affinity (IC50=2.7 μg/ml) for penicillin binding protein 2' (PBP2') of MRSA and potent activity against Gram-negative bacteria as well.
    在我们探索具有优异抗甲氧西林耐药黄色葡萄球菌(MRSA)抗菌活性的新的头孢菌素生物的过程中,我们对具有l-甲基咪唑[1, 2-b]吡咯噻啉-6-基团的C-3链接间隔物进行了修改,其位于C-3'位置,以及具有2-(5-基-1, 2, 4-噻二唑-3-基)-2(Z)-环戊基氧基亚胺乙酰基团的C-7位置。最优间隔物是19a和29aa中的(E)-2-乙烯基和(E)-2-乙烯基,分别其抗MRSA活性是头孢佐芬(CZOP)活性的16到32倍。我们针对(E)-2-乙烯基和(E)-2-乙烯基间隔物,进一步修改了C-7酰基部分的烷氧亚胺基团和C-3'位置的1-烷基咪唑[1, 2-b]吡咯噻啉基团,并研究了这些衍生物的构效关系(SAR)。因此,我们选择了7β-[2-(5-基-1, 2, 4-噻二唑-3-基)-2(Z)-甲氧基亚胺乙酰基]-3-[(E)-2-(l-甲基咪唑[1, 2-b]吡咯噻啉-6-基)乙烯基]-3-头孢菌素-4-羧酸酯(29ca)作为新的抗MRSA注射用头孢菌素候选物进行进一步的生物评价。所选择的29ca在体外和体内的抗MRSA活性与万古霉素VCM)相当,对MRSA的青霉素结合蛋白2'(PBP2')具有高亲和力(IC50=2.7 μg/ml),并对革兰阴性细菌同样表现出强大的活性。
