Abstract

A mild and efficient method for the synthesis of 1,8-dioxodecahydroacridines has been developed. The synthesis proceeds via a three-component reaction of a 1,3-dione, an aldehyde and an amine, under solvent-free conditions, catalyzed by tris(pentafluorophenyl)borane [B(C6F5)3]. The mildness of the catalyst was demonstrated­ by studying the reaction of 1,3-cyclohexanedione with various aldehydes and amines which gave the 1,8-dioxodecahydroacridines in high yields.
