TLDR
In this article, a tricyclic system with 1,3-butadienes and cyclopentadiene was synthesized using double Diels-Alder reaction.Abstract:
Thermal reaction of coumalic acid with 1,3-butadienes gave after diazomethane treatment dimethyl tricyclo[32102,7]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 studiedread more

Synthesis of tricyclic ketones by copper-catalyzed cyclization of monocyclic olefinic diazoketones
TL;DR: In this article, the double bond of monocyclic olefins was used for the intramolecular trapping of intermediates of the copper-ketocarbene type, leading to a variety of tricyclic ketones.
