近三十年来,人们对光学异构体在药物、食品添加剂、昆虫信息素、农药和香料等领域中的应用做了广泛地研究,结果表明,在大多数情况下,光学异构体的性质不尽相同,其差别表现为1>生物活性不同;2>转运机制不同;3>可能的代谢途径不同。这样如何获得一种单一构型的光学异构体就成为化学家研究的重点课题。不对称反应的发现和近年来取得的成就为获得单一构型的光学异构体提供了一条简捷而经济的途径。手性过渡金属络合物催化的不对称反应人
For nearly thirty years, extensive research has been conducted on the use of optical isomers in the fields of medicine, food additives, insect pheromones, pesticides and fragrances. The results show that in most cases, the properties of optical isomers Not the same, the difference is manifested as 1> different biological activity; 2> different transport mechanisms; 3> possible metabolic pathways. How to obtain a single configuration of optical isomers has become a chemist research priorities. The discovery of asymmetric reactions and the achievements made in recent years provide a simple and economical way to obtain optical isomers of a single configuration.
