Demonstrates effective synthesis of CF3-containing heterocycles in 1,6-dienes, indicating a new method for creating complex molecules.
A visible‐light photoredox‐catalyzed tandem trifluoromethylation/cyclization/remote oxidation of 1,6‐dienes has been achieved. A broad range of trifluoromethyl group‐containing tetrahydrofurans or tetrahydropyrroles could be generated in good yields and with excellent diastereoselectivity by using dimethyl sulfoxide (DMSO) as the oxidant. The mild and facile protocol affords direct access to trifluoromethyl group‐bearing tetrahydrofurans and tetrahydropyrroles via difunctionalization of olefins. magnified image
