The synthesis of a number of grisa-3′,5′-diene-2′,3-diones by oxidative coupling of substituted 2,2′-dihydroxy-4-methoxybenzophenones is described. The rearrangement of these grisadienediones to depsidones under basic, acidic, and thermal conditions is described and the mechanisms of these reactions are discussed. It is proposed that depsidone biosynthesis involves the oxidative coupling of benzophenones
描述了通过取代的2,2'-二羟基-4-甲氧基二苯甲酮的氧化偶联合成许多grisa-3',5'-二烯-2',3-二酮的方法。描述了在碱性,酸性和热条件下将这些grisadienediones重排为depsedones,并讨论了这些反应的机理。有人提出二甲双胍的生物合成涉及二苯甲酮与三聚体二烯的氧化偶联,然后再重排成二甲双烯。
