  摘要：

  我们成功开发了一种利用容易获得的N- (2-氨基苯基)苯甲酰胺和异氰酸苯酯合成仲酰胺的有效方法。值得注意的是，离去基团可以很容易地恢复为羰基化的N-杂环，这在制药应用中具有显着的相关性。该策略的关键涉及异氰酸苯酯的连续亲核/分子内加成过程，然后进行转酰胺基化。此外，该方案还具有原子经济性、实用性、一锅两步反应以及底物制备简便等特点。

  Cyclooxygenase-1-Selective Inhibitors Are Attractive Candidates for Analgesics That Do Not Cause Gastric Damage. Design and in Vitro/in Vivo Evaluation of a Benzamide-Type Cyclooxygenase-1 Selective Inhibitor

  摘要：

  Although cyclooxygenase-1 (COX-1) inhibition is thought to be a major mechanism of gastric damage by nonsteroidal anti-inflammatory drugs (NSAIDs), some COX-1-selective inhibitors exhibit strong analgesic effects without causing gastric damage. However, it is not clear whether their analgesic effects are attributable to COX-1-inhibitory activity or other bioactivities. Here, we report that N-(5-amino-2-pyridinyl)-4(trifluoromethyl)benzamide (18f, TFAP), which has a structure clearly different from those of currently available COX-1-selective inhibitors, is a potent COX-1-selective inhibitor (COX-1IC(50) = 0.80 +/- 0.05 mu M, COX-2IC(50) = 210 I mu M). This compound causes little gastric damage in rats even at an oral dose of 300 mg/kg, though it has an analgesic effect at as low a dose as 10 mg/kg. Our results show that COX-1-selective inhibitors can be analgesic agents without causing gastric damage.

  An efficient Cu(II)-vasicine catalytic system has been developed for intramolecular CN bond formation. In this way, regioselective 2-amination of o-haloanilides with aqueous ammonia in EtOH has been achieved. This strategy provides several advantages, such as good regioselectivity, high yields and functional group tolerance.

  We have successfully developed an efficient method for synthesizing secondary amides utilizing easily accessible N-(2-aminophenyl)benzamide and phenyl isocyanate. Notably, the leaving group can be easily recuperated as a carbonylated N-heterocycle, which holds notable relevance in pharmaceutical applications. The crux of this strategy involves a sequential nucleophilic/intramolecular addition process
