    Relative hepatotoxicity of 2-(substituted phenyl)thiazoles and substituted thiobenzamides in mice: evidence for the involvement of thiobenzamides as ring cleavage metabolites in the hepatotoxicity of 2-phenylthiazoles
    摘要:
    The hepatotoxicity of the 3 isomers of para-substituted thiobenzamides and the 3 isomers of 2-(para-substituted phenyl)-4-methylthiazoles was evaluated in mice depleted of glutathione (GSH) by pretreatment with buthionine sulfoximine (BSO). In accordance with previous studies with the rat, p-methoxythiobenzamide was more toxic than thiobenzamide, and conversely p-chlorothiobenzamide was markedly less toxic as assessed by serum alanine aminotransferase (ALT) activity. The hepatotoxicity of 2-phenyl-4-methylthiazole was also altered by the addition of para-substituents to the phenyl ring in the same way as observed for thiobenzamide derivatives: the rank order of toxicity was 4-methylthiazoles having p-methoxyphenyl > phenyl much greater than p-chlorophenyl at the 2-position. This good correlation of the rank order of hepatotoxicity between series of 2-(para-substituted phenyl)-4-methylthiazoles and para-substituted thiobenzamides supports the concept that thiobenzamides as ring cleavage metabolites play a role in the hepatotoxicity of 2-phenylthiazole derivatives.

    The domino sequence for the synthesis of 2‐imino‐1H‐imidazol‐5(2H)‐ones includes aza‐Michael addition, intramolecular cyclization, CC bondcleavage, 1,2‐rearrangement, and aerobic dehydrogenation reaction, whereas the domino sequence for the synthesis of quinoxalines includes aza‐Michael addition, intramolecular cyclization, elimination reaction, and CC bondcleavage reaction. The two domino reactions
    尽管2-亚氨基-1 H-咪唑-5(2 H)-酮在代谢中具有重要的生物学活性,但很少对其合成进行研究。喹喔啉作为药物化学中的“特权支架”已被广泛研究,但是新型有效合成方法的开发仍然非常有吸引力。本文中,我们开发了两个铜催化的多米诺反应,用于合成2–亚氨基-1 H-咪唑-5(2 H)-ones和喹喔啉,涉及CC键断裂,并带有1,3-二羰基单元。离开小组。合成2-亚氨基1 H-咪唑5(2 H)-1的多米诺序列包括aza-Michael加成,分子内环化,C C键裂解,1,2-重排,和有氧脱氢反应,而对于喹喔啉的合成的多米诺序列包括氮杂-迈克尔加成,分子内环化,消除反应,和C  C键断裂反应。这两个多米诺反应具有显着的优势,包括高效,温和的反应条件以及对各种官能团的高度耐受性。

    Abstract

    Glycerol is one of the important biomass‐derived feedstocks and the high‐value utilizations of glycerol have attracted much attentions in recent years. Herein, we report a manganese catalyzed dehydrogenative coupling of glycerol with amines for the synthesis of substituted 2‐methylquinoxalines, 2‐ethylbenzimidazoles, and α‐aminoketones without any external oxidant. In these reactions, NHC‐based pincer manganese complex featuring a pyridine backbone displayed high catalytic activity and selectivity, in which hydrogen and water were produced as the only by‐products using glycerol as a C3 synthon.
