A novel HF2CSO2Na/Ph2PCl/Me3SiCl system is disclosed for the late-stage direct difluoromethylthiolation of C-sp2 and C-sp3 nudeophiles. Difluoromethylthiolation of phenols and naphthols proceeded nicely under this system to regioselectively provide corresponding SCF2H compounds in good yields. Other substrates such as indoles, pyrroles, pyrazoles, enamines, ketones, and beta-keto esters were also transformed to corresponding SCF2H products in good yields. The late-stage direct difluoromethylthiolation of a number of natural products and pharmaceutically attractive molecules was also achieved.
