Abstract
Abstract An efficient, chromatography-free asymmetric synthesis of (R)-3-amino-1,1,1-trifluoropropan-2-ol was developed for large scale production of a cholesterol ester transfer protein (CETP) inhibitor. The synthesis features a new efficient route to a β-amino trifluoromethylketone involving a modified Dakin–West reaction followed by an asymmetric hydrogenation or an enzymatic reduction of the resulting ketone to the alcohol.
