내용: In recent years, the trifluoromethylthio (SCF3) group has attracted much attention due to its strong electron-withdrawing effect and extremely high lipophilicity. These properties of the SCF3 group can enhance the transmembrane permeation of SCF3-containing organic molecules, that is of great interest to the field of pharmaceuticals and agrochemicals. In addition, α,β-unsaturated carbonyl compounds are important substrates used in many organic reactions, such as cycloadditions, conjugate additions and cascade reactions. Therefore, the incorporation of the SCF3 group into α,β-unsaturated carbonyl compounds is important in that it is capable of synthesizing a variety of bioactive compounds having increased bioavailability. Here, α-trifluoromethylthiolation of α,β-unsaturated carbonyl compounds will be presented.
