手征性硫代磷酸及其衍生物的研究(Ⅰ)——O-乙基-O-苯基硫代磷酸的拆分及其手征性硫(醇)代酯的合成
STUDIES ON CHIRAL THIOPHOSPHORIC ACIDS AND THEIR DERIVATIVES-I——THE RESOLUTION OF O-ETHYL-O-PHENYL PHOSPHOROTHIOIC ACID AND THE SYNTHESIS OF ITS CHIRAL THIOL-ESTERS
【摘要】 以奎宁为拆分剂,在甲醇溶液中,将O-乙基-O-苯基硫代磷酸(Ⅰ)拆分成一对对映异构体。 旋光活性的酸在醇钠存在下与卤代烷反应,得到O-乙基-O-苯基-S-烷基硫代磷酸酯(Ⅱ)的对映异构体。 其中Ⅱ-b和Ⅱ-c两对对映异构体为杀虫剂。
【Abstract】 Through quinine salt O-ethyl-O-phenyl phosphorothioic acid( I ) has been successfully resolved in methanol solution:The enantiomers of the acid, on reacting with alkyl halides, RX, in the presence of sodium alcoholate, yielded the enantiomers of O-ethyl-O-phenyl-S-alkyl phosphorothioate (Ⅱ):whereOf these, the two pairs Ⅱ-b and Ⅱ-c are insecticides.
