Intramolecular 1,3-dipolar cycloaddition of alkyl azide enones and rearrangements of the triazoline intermediates. Formal total synthesis of (.+-.)-desamylperhydrohistrionicotoxin
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.
