  Multisubstrate inhibitors of dopamine .beta.-hydroxylase. 1. Some 1-phenyl and 1-phenyl-bridged derivatives of imidazole-2-thione

  摘要：

  The synthesis and characterization of some 1-(phenylalkyl)imidazole-2-thiones as a novel class of "multisubstrate" inhibitors of dopamine beta-hydroxylase (DBH) are described. These inhibitors incorporate structural features that resemble both tyramine and oxygen substrates, and as evidenced by steady-state kinetics, they appear to bind both the phenethylamine binding site and the active site copper atom(s) in DBH. A series of structural congeners that incorporate different bridging chain lengths between the phenyl ring (dopamine mimic) and the imidazole-2-thione group (oxygen mimic) define the optimum distance for inhibitory potency and the likely intersite distance in the DBH active site. Additional bridging analogues were prepared to determine the active site bulk tolerance and the effects of heteroatom replacement.

• Selective Cleavage of Inert Aryl C–N Bonds in <i>N</i>-Aryl Amides
  作者：Zhiguo Zhang、Dan Zheng、Yameng Wan、Guisheng Zhang、Jingjing Bi、Qingfeng Liu、Tongxin Liu、Lei Shi

  A highly selective, IBX-promoted reaction has been developed for the oxidative cleavage of inert C(aryl)–N bonds on secondary amides while leaving the C(carbonyl)–N bond unchanged. This metal-free reaction proceeds under mild conditions (HFIP/H2O, 25 °C), providing facile access to various useful primary amides, some of which would be otherwise unattainable using conventional aminolysis and hydrolysis

  已经开发出一种高度选择性的IBX促进的反应，用于氧化裂解仲酰胺上的惰性C（芳基）-N键，同时保持C（羰基）-N键不变。这种无金属的反应在温和的条件下（HFIP / H 2 O，25°C）进行，可以轻松获得各种有用的伯酰胺，而使用常规的氨解和水解方法则无法实现其中的某些。

  Addition of pyridine to benzoylcarbonitrile oxide affords a fragile zwitterionic adduct, which slowly reverts to the addends, leading ultimately to benzoyl isocyanate and products deriving from it. A moderately stable cycloadduct is obtained in the reaction with isoquinoline.
