摘要
研究了手性酒石酸衍生物D-或L-二对甲氧基苯甲酰酒石酸(DMTA)的合成工艺。在三氟化硼-乙醚络合物催化下,D-(或L-)酒石酸与对甲氧基苯甲酰氯和二氯亚砜作用生成D-(或L-)二对甲氧基苯甲酰酒石酸酐,然后酸酐在丙酮-水体系中水解成D-(或L-)二对甲氧基苯甲酰酒石酸,两步总收率82.73%,光学纯度大于99%。
The process for synthesis of D-(or L-)-bis (4-methoxybenzoyl)-tartarie acid (DMTA) was studied. In the presence of catalytic amount of boron fluoride ethyl ether, the reaction of D-(or L-)-tartaric acid with 4-methoxybenzoyl chloride and thionyl dichloride gave D-(or L-)-bis(4-methoxybenzoyl)-tartaric anhydride that was then treated with water to afford D-(or L-)-bis (4-methoxybenzoyl)-tartaric acid. DMTA was synthesized with high yield (82.73%) and high enantioselectivity (〉99%ee).
