Methyl (±)-2-acetoxy-3-carboxypropionate has been prepared from (±)-malic acid and used in crossed Kolbe electrolyses to prepare dimethyl (±)-2-acetoxydodecane-1,12-dioate and three methyl 2-acetoxyalkanoates. Dimethyl and diethyl meso-2,5-diacetoxyadipates have been isolated from the Kolbe electrolyses of methyl and ethyl (±)-2-acetoxy-3-carboxypropionates respectively, and the presence of the corresponding
由(±)-苹果酸制得(±)-2-乙酰氧基-3-羧基丙酸甲酯,并用于交叉Kolbe电解中以制备(±)-2-乙酰氧基十二烷-1,12-二酸二甲酯和3种2-乙酰氧基链烷酸甲酯。 。分别从甲基和(±)-2-乙酰氧基-3-羧基丙酸乙酯的Kolbe电解质中分离了内消旋-2,5-二乙酰氧基己二酸二甲酯和二乙基,相应的(±)-2,5-二乙酰氧基己二酸酯的存在已建立。氢化锂铝将二乙基内消旋-2,5-二乙酰氧基己二酸酯还原得到内消旋-己烷-1,2,5,6-四醇。
