(Z)-3-[2H1]-Phenylprop-2-enone is isomerised by hydroperoxide to an equimolar mixture of the (Z)- and (E)-isomers prior to epoxidation. Poly-(L)-leucine (10 mole %) accelerates the addition of hydroperoxide by an order of magnitude and sequesters hydroperoxide from THF.
(Z)-3-[2H1]-苯基丙-2-烯酮在环氧化之前通过氢过氧化物异构化为(Z)-和(E)-异构体的等摩尔混合物。聚-(L)-亮
氨酸(10 摩尔%)可将氢过氧化物的添加加速一个数量级,并从 THF 中螯合氢过氧化物。
