Deoxy-functionalization of alcohols represents a class of reactions that has had a profound impact on modern medicine. In particular, deoxyfluorination is commonly employed as a means to incorporate high-value fluorine atoms into drug-like molecules. Recently, the trifluoromethyl (CF3) group has garnered attention from medicinal chemists due to its ability to markedly improve the pharmaceutical properties of small-molecule drug candidates. To date, however, there remains no general means to accomplish the analogous deoxygenative trifluoromethylation of alcohols. We report herein a copper metallaphotoredox-mediated direct deoxytrifluoromethylation, wherein alcohol substrates are activated in situ by benzoxazolium salts for C(sp3)-CF3 bond formation.
