Isolation and Reactivity of Trifluoromethyl Iodonium Salts.

The strategic incorporation of the trifluoromethyl (CF3) functionality within therapeutic or agrochemical agents is a proven strategy for altering their associated physicochemical properties (e.g., metabolic stability, lipophilicity, and bioavailability).

Single-operation deracemization of 3H-indolines and tetrahydroquinolines enabled by phase separation.

The single-operation deracemization of 3H indolines and tetrahydroquinolines is described. An asymmetric redox approach was employed, in which a phosphoric acid catalyst, oxidant, and reductant are present in the reaction mixture. The simultaneous presence of both oxidant and reductant was enabled by phase separation and resulted in the isolation of highly enantioenriched starting materials in high yields.
