Mechanistic studies of tandem regioselective decarboxylation, prenyl transfer, and aromatization reactions of prenyl dioxinone diketo-carboxylates to provide 3-prenyl-resorcylate derivatives are described. Studies of the effects of concentration and the base employed as well as the results of cross-over experiments were all found to be consistent with the reaction proceeding largely via an intermolecular
描述了串联的区域选择性脱羧,异戊二烯基转移和异戊二烯二酮二酮羧酸酯提供3-异戊烯基-间苯二酸酯衍生物的芳构化反应的机理研究。发现对浓度和所用碱的影响的研究以及交叉实验的结果均与很大程度上通过分子间反应途径进行的反应一致。
