  Prochiral ethylenically unsaturated substrates are converted to chiral epoxides by reaction with optically active hydroperoxides in the presence of transition metal catalysts. For example, chiral glycidol is obtained by asymmetric epoxidation of allyl alcohol using optically active ethyl benzene hydroperoxide and a titanium alkoxide/tartrate catalyst. The chiral epoxide products are versatile synthetic intermediates.

  手性乙烯基不饱和底物在过渡金属催化剂的作用下，通过与光学活性过氧化氢反应转化为手性环氧化物。例如，使用光学活性过氧化乙苯氢氧化物和钛烷氧基/酒石酸催化剂对烯丙基醇进行不对称环氧化反应可获得手性缩水甘油。手性环氧化物产品是用途广泛的合成中间体。
