A convenient approach towards enantiopure (R) and (S) isomers of 2,2,2-trifluoro-1-(heteroaryl)ethanols was developed. The enzyme-catalyzedkineticresolution of the corresponding racemic mixtures was achieved by using a two-step protocol that involved an acylation and a hydrolysis step in the presence of Burkholderia cepacia and CAL-B lipase (Candida antarctica lipase B), respectively.
