Reactions of 1,5-Diketones with Ammonia and Its Derivatives. (Review)

Published data and the authors' own experimental results on the reaction of aliphatic, semicyclic, and oxosemicyclic 1,5-diketones and alkylidene- and arylidene-2,2-dicyclanones with ammonia, ammonium acetate, and XNH2 derivatives, where X = Alk, Ar, OH, NH2, PhNH, ArCONH, and CHO, are reviewed. The characteristics and the relationships governing the transformations into azaheterocycles in relation to the nature of the reagents and the reaction conditions are discussed.
