Thermal reaction of coumalic acid with 1,3-butadienes gave after diazomethane treatment dimethyl tricyclo[3.2.1.02,7]oct-3-ene-2,4-dicarboxylate via double Diels-Alder reaction. This represents the simplest synthesis of such a tricyclic system. The reaction with cyclopentadiene was also studied.
香豆酸与1,3-丁二烯的热反应在重氮甲烷处理后通过双重Diels-Alder反应得到三环[3.2.1.02,7]oct-3-ene-2,4-二羧酸二甲酯。这代表了这种三环系统的最简单合成。还研究了与环戊二烯的反应。
