• W2763547386 abstract "The trifluoromethylthio (SCF3) group enjoys a privileged role in the field of drug discovery because its incorporation into a drug molecule often leads to significantly improved pharmacokinetics and efficacy. In spite of its prime importance in drug discovery, the stereospecific introduction of the SCF3 group into target molecules has remained an unmet challenge. A major breakthrough was made in 2013 when Rueping and Shen simultaneously and independently disclosed natural Cinchona alkaloid catalyzed asymmetric electrophilic trifluoromethylthiolation of β-keto esters. However, two key issues remain obscure. (a) What is the preferred mode of catalysis? (b) How is asymmetric induction accomplished? Here we report an in-depth computational exploration into the mechanism and origin of stereoinduction in Cinchona alkaloid catalyzed trifluoromethylthiolation of β-keto esters with N-trifluoromethylthiophthalimide as electrophilic SCF3 source. Three mechanistic possibilities, i.e., (a) the transfer-trifluoromethyl..." @default.
