  Transformations of (1E,3E)-1-(benzoylamino)-4-(dimethylamino)buta-1,3-diene-1,2,3-tricarboxylates into pyridine and pyrrole derivatives

  摘要：

  New, highly functionalised (1E,3E)-1-(benzoylamino)-4-(dimethylamino)buta-1,3-diene-1,2,3-tricarboxylates proved to be useful and versatile reagents in the formation of highly substituted pyridine, N-aminopyridine, pyrrole and pyrido[3,4-c]pyridazine derivatives. The formation of the particular type heterocyclic system is dependent on the starting (1E,3E)-1-(benzoylamino)-4-(dimethylamino)buta-1,3-diene-1,2,3-tricarboxylate. By an appropriate choice of different ester groups it is possible to drive the reactions towards the formation of either pyridine or pyrrole derivatives. (C) 2008 Elsevier Ltd. All rights reserved.
