Direct Catalytic Trifluoromethylthiolation of Boronic Acids and Alkynes Employing Electrophilic Shelf-Stable N-(trifluoro-methylthio)phthalimide

摘要

A new and safe method for the synthesis of N-(trifluoromethylthio)phthalimide, a convenient and shelf-stable reagent for the direct trifluoromethylthiolation, has been developed. N-(Trifluoromethylthio)ph'thalimide can be used as an electrophilic source of F3CS~+ and reacts readily with boronic acids and alkynes under copper catalysis. The utility of CF S-containing molecules as biologically active agents, the mild reaction conditions employed, and the high tolerance of functional groups demonstrate the potential of this new methodology to be widely applied in organic synthesis as well as industrial pharmaceutical and agrochemical research and development.
