一个新的金属催化的烯丙醇不对称环氧化(asymmetric epoxidation A.E)似比以前所有烯丙醇不对称环氧化方法为好。这个比较简单的新方法引人注意的一个方面是对映选择性非常之高而且所需试剂(+)-或(-)-酒石酸二酯,四异丙氧钛和叔丁基过氧化氢都容易得到。自从 1980年 Sharpless等发现这个方法以
A new metal-catalyzed asymmetric epoxidation of A.E. appears to be better than all previous allylic asymmetric epoxidation methods. One aspect that has attracted the attention of this relatively simple new method is that the enantioselectivity is very high and the required reagents (+) - or (-) - tartaric acid diester, titanium tetraisopropoxide and tert-butyl hydroperoxide are both Easy to get Sharpless et al. Found this method since 1980
