Résumé

An efficient and versatile synthetic palladium-catalyzed sp² C, H bond activation approach for the preparation of a series of C8-benzyl xanthines has been developed using benzyl chlorides as coupling partners. The reactions take place rapidly in 1,4-dioxane and proceed in the presence of [PdCl₂(MeCN)₂]/P(o-tolyl)₃ as a catalyst system and Cs₂CO₃ as a base to afford good to excellent yields of the corresponding C8-benzylated xanthines of biological interest.
