An enantio- and diastereoselective carbonyl-ene reaction catalyzed by chiral scandium pyridyl bis(oxazoline) (pybox) complexes has been developed. Uniformly high enantiomeric excesses and good yields were observed. Use of trisubstituted olefins generated the syn product in high enantio- and diastereoselectivity.
已经开发了由手性钪吡啶基双(恶唑啉)(pybox)配合物催化的对映选择性和非对映选择性羰基烯反应。观察到均匀高的对映体过量和良好的产率。三取代烯烃的使用以高对映选择性和非对映选择性产生了合成产物。
