Synthèse du système cyclique de l'aza-triquinane linéaire par trois cyclisations radicalaires en cascade

Abstract Treatment of the acyclic allyl-octa-4,7-dienyl N-chloroamine 5 by titanium trichloride induces a chain process including three consecutive regio- and stereo-selective homolytic cyclisations. As a result of these selectivities, the main product of the reaction is an original linear cis-syn-cis aza-triquinane, the structure of which was assigned by high field (400 MHz) Nuclear Magnetic Resonance study.
