  改良的Curtius反应：直接分离游离胺的有效简便方法

  摘要：

  Curtius重排和相关的反应通常用于将羧酸转化为相应的伯胺。但是，该反应通常需要苛刻的条件才能将异氰酸酯中间体水解为胺，并且由于中间体的反应性，还可能因形成相应的脲而受到污染。我们发现，通过用三甲基硅烷醇钠淬灭异氰酸酯中间体，可以在水性处理后分离出游离胺。这种温和而快速的步骤可在一锅中以良好的产率提供游离胺。

  Orally active .beta.-lactam inhibitors of human leukocyte elastase-1. Activity of 3,3-diethyl-2-azetidinones

  摘要：

  A thorough analysis of the mechanism of inhibition of human leukocyte elastase (HLE) by a monocyclic beta-lactam and the mechanism of beta-lactam hydrolysis led to the preparation of potent and highly stable inhibitors of HLE. This work led to the identification of 4-[(4-carboxyphenyl)-oxy]-3,3-diethyl-1-[[(phenylmethyl)amino]carbonyl]-2-azetidinone (2) as the first orally active inhibitor of human leukocyte elastase (HLE). Analogs of 2 with different substituents on the urea N were synthesized and evaluated for their activity in vitro against HLE as well as in vivo in a hamster lung hemorrhage model. Compounds with a methyl or a methoxy group in the para position of the benzene ring were very potent in both assays. The results are discussed on the basis of the proposed model for the binding of this class of inhibitors to HLE and a possible mechanism of inhibition is presented.
