ylides utilizing nucleophilic halide reagent and electrophilic SCF3 reagent. This cascade reaction is mild, highly practical, easy to manipulate, uses catalyst-free conditions, and demonstrates a wide substrate range with excellent functional group tolerance, furnishing E-selective products in good to high yields. The synthetic utility of this approach is documented through gram-scale preparation and
四取代的三氟甲基硫醇化的烯烃可通过使用亲核卤化物试剂和亲电的SCF 3试剂通过硫酰化物的氯三氟甲基硫醇化直接完成。该级联反应温和,高度实用,易于操作,使用无催化剂条件,并显示了广泛的底物范围,具有出色的官能团耐受性,可提供高收率的E选择性产品。通过克级制备和药物相关化合物的后期修饰,证明了该方法的合成效用,使其适用于药物发现。
