摘要

Abstract: Aliphatic azides were captured intramolecularly by carbocations, producing aminodiazonium ion intermediates. Carbon-to-nitrogen rearrangement then occurred, generating bridged-or fused-bicyclic a-amino carbocations or iminium ions, depending on the geometry about the C (+)-N bond. In the bridged systems, rapid elimination of the a- amino carbocations produced twisted enamines with 1-azabicyclo [3.2. 2] nonene, 1- ...
