Abstract
Reaction of bicyclic conjugated dienones (II, III, IV, V, and VI) with hydrazoic acid in PPA was carried out and the results were summarized in Table I. All products were probably formed by action of two molar equivalents of hydrazoic acid. From the substrates (I and III), the aldehyde-lactams (XI, XIX, and XX) were obtained whose formation is the first observation in this reaction.
