An unprecedented electrochemical heterodifunctionalization of α-CF alkenes with benzenesulfonyl hydrazides was accomplished in this work, wherein a β-sulfonyl and a α-hydroxyl group were simultaneously incorporated across the olefinic double bond in a single operation. Consequently, a series of potentially medicinally valuable and densely functionalized α-trifluoromethyl-β-sulfonyl tertiary alcohols were assembled under mild conditions. Electrochemically-driven oxidative 1,2-difunctionlization of electron-deficient alkenes well obviates the need for oxidizing reagents, thus rendering this protocol more eco-friendly.
在这项工作中,首次实现了 α-CF 烯烃与苯磺酰肼的电化学异双官能化反应,其中在单个操作中同时在烯烃双键的两侧引入了β-磺酰基和α-羟基。因此,在温和条件下,成功地组装了一系列具有潜在药用价值和高度官能化的α-三氟甲基-β-磺酰基叔醇。电化学驱动的缺电子烯烃的氧化 1,2-双官能化很好地避免了对氧化剂的需求,从而使该方法更加环保。
