easily prepared from carbonyl compounds and 1-chloroalkyl phenyl sulfoxide, with 1 equivalent of butyllithium at low temperature gave epoxides in good yields. The similar α,β-epoxy sulfoxides having an arylmethyl group at the α-position gave 3-aryl-allylic alcohols upon treatment with excess butyllithium at −70 °C. These reactions offer a simple and useful approach to the synthesis of epoxides and 3-aryl-allylic
α,β-环氧亚砜很容易由羰基化合物和 1-氯代烷基苯基亚砜制备,在低温下用 1 当量的丁基锂脱亚硫基得到环氧化物,产率很高。在-70℃下用过量丁基锂处理后,在α-位具有芳甲基的类似α,β-环氧亚砜得到3-芳基-烯丙醇。这些反应为从羰基化合物合成环氧化物和 3-芳基-烯丙醇提供了一种简单而有用的方法。
