Intramolecular 1,3-dipolar cycloaddition of alkyl azide enones and rearrangements of the triazoline intermediates. Formal total synthesis of (.+-.)-desamylperhydrohistrionicotoxin
The thermal rearrangement of alpha-(omega-azidoalkyl) enones has been investigated. A variety of these substrates were synthesized and subjected to thermal rearrangement to investigate the scope and generality of their transformation to bicyclic lactams.

A new one-pot procedure for the preparation of aminoenone from chloroalkyl enone and sodium azide was demonstrated. The structure of the presumed triazoline intermediate in this process was confirmed by X-ray analysis for the first time. As the application of this methodology, the synthesis of polycyclic alkaloid hexahydroapoerysopine (1a) was achieved through an efficient synthetic route.
