Abstract

Tri-and Tetracyclic Azepine Derivatives by Thermally Induced Cyclization of Aminoallenes and Semicyclic 2-Dienamines.-It offers an efficient route to tri-and tetracyclic azepines. The outcome of the cyclization of 2-dienamines strongly depends on the ring size of the enamine moiety and the nature of the aryl substituent at C-2'. -(REINHARD, R.; GLASER, M.; NEUMANN, R.; MAAS, G.; J.
