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.
开发了一种温和有效的合成 1,8-二氧十氢吖啶的方法。该合成通过 1,3-二酮、醛和胺在无溶剂条件下、三(五氟苯基)硼烷 [B(C6F5)3] 催化下进行三组分反应进行。通过研究1,3-环己二酮与各种醛和胺的反应证明了该催化剂的温和性,该反应以高收率生成1,8-二氧代十氢吖啶。
