不对称有机反应的研究是有机化学中一个很有意义的领域,它对反应机理的考察,构型的测定以及制备光学活性化合物都有着重大的作用。虽然早在上世纪末就进行过醣类的不对称反应,但直到本世纪五十年代一些反应的立体模型建立以后才有较大的发展,六十年代中 Asymmetric organic reaction is one of the most significant areas in organic chemistry. It has a significant role in the investigation of reaction mechanism, configuration determination and preparation of optically active compounds. Although the asymmetric reaction of sugars was carried out as early as the end of the last century, it has not been developed until after the establishment of the three-dimensional model of some reactions in the 1950s. In the mid-1960s
