【摘要】 1,2,1＇,2＇-双蒽醌-3,12-二羧酸(1)是一个π-共轭体系芳环化合物,内环酮基由于受空间效应和共振效应的影响,不能被还原成相应的醇或相应的碳氢基团,却成了不常见的内“双氧桥”化合物(4)。化合物2,3,4的结构已经确定,并对1的还原机理进行了初步讨论。更多还原

【Abstract】 1,2,1′,2′-Dianthraquinone-3,12-dicarboxylic acid(1)is a π-con-jugated cyclic compound.Due to the steric and the resonance effect,the endo-ketone of1 can not be reduced to the corresponding dihydroxy compound or hydrocarbon,butinstead,it is reduced to the unusual“O-endocyclic”compound(4).The structures of 2,3,4 are also ascertained and the reduction mechanism discussed.更多还原
