Synthesis of gamma-DDB, which is another family member of gamma-DDB (dimethyl 4,4(')-dimethoxy-5,6,5('),6(')- dimethylenedioxybiphenyl-2,2(')-dicarboxylate), is described. The unsymmetric isomer (gamma-DDB) was constructed by a linker-directed intramolecular Ullmann coupling reaction, followed by the cleavage of the linker and re-esterification.
γ-DDB的合成,它是γ-DDB的另一个家族成员(二甲基4,4(')-二甲氧基-5,6,5('),6(')-二亚甲基二氧基联苯-2,2(')-二羧酸酯),进行了说明。不对称异构体(γ-DDB)通过连接子指导的分子内Ullmann偶联反应构建,然后裂解连接子并重新酯化。
