A one-pot synthesis of epoxides from commercially available benzyl alcohols and aldehydes is described. The reaction proceeds through in situ generation of sulfonium salts from benzyl alcohols and their subsequent deprotonation for use in Corey-Chaykovsky epoxidation of aldehydes. The generality of the method is exemplified by the synthesis of 34 epoxides that were made from an array of electronically

We report herein a formal asymmetricepoxidation of arylalkanes enabled by a one-pot dual-catalysts system comprising a pincer Ir catalyst for alkane dehydrogenation-alkene isomerization (AD-ISO) and a chiral ketone catalyst for asymmetric alkene epoxidation. This protocol provides a catalytic method for the synthesis of aryl epoxides in useful yields with high regio- and stereoselectivity directly
我们在此报道了一种通过一锅双催化剂系统实现的芳基烷烃的正式不对称环氧化,该系统包括用于烷烃脱氢-烯烃异构化 (AD-ISO) 的钳形 Ir 催化剂和用于不对称烯烃环氧化的手性酮催化剂。该协议提供了一种催化方法,用于直接从容易获得的烷基芳烃中合成具有高区域和立体选择性的有用产率的芳基环氧化物。环氧化产物的立体特异性衍生允许获得各种对映体富集的化合物。
