The Rh(III)-catalyzed asymmetric reduction of α-trifluoromethyl ketones through transfer hydrogenation was developed under mild conditions to access a series of enantioenriched cistrifluoromethyl alcohols via a dynamic kinetic resolution process. The reaction was efficiently performed in the green solvent 2-MeTHF with HCO 2 H/Et 3 N (1 : 1) as the hydrogen source. High yields, alongside excellent diastereo-and enantioselectivities were obtained for the synthesis of CF 3 -chromanol, CF 3 -indanol and CF 3 -tetralol derivatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
