Chiral selenide-catalyzed oxytrifluoromethylthiolation of aliphatic internal alkenes by a formally intermolecular strategy is disclosed, affording CF3S 1,3-amino alcohol and 1,3-diol derivatives with high regio-, enantio-, and diastereoselectivities. The reactions are promoted by a neighboring imide or ester group on substrates via a six-membered ring transition state. This assistance strategy is also
公开了通过形式上的分子间策略手性硒化物催化的脂肪族内烯烃的氧三氟甲基硫醇化,提供了具有高区域,对映体和非对映选择性的CF 3 S 1,3-氨基醇和1,3-二醇衍生物。底物上相邻的酰亚胺或酯基团通过六元环过渡态促进了反应。该辅助策略也成功地应用于内部烯烃的区域和非对映选择性的氧卤官能化以及炔烃的转化。
