  Novel formation of 1,3-oxazepine heterocycles via palladium-catalyzed intramolecular coupling reaction

  摘要：

  The oxazepine ring systems containing pyridazinone moiety were constructed via palladium-catalyzed intramolecular coupling reaction. The best conditions for this reaction were Pd(OAc)(2) as a palladium source, 1,1'-bis(diphenylphosphino)-ferrocene (DPPF) as the ligand, and K2CO3 as base at 80 degrees C in toluene. The products have potential applications as biological and medicinal relevant compounds. (c) 2006 Elsevier Ltd. All rights reserved.
