correctly understand the effect of fluorination on bioactivity. Here we report an easy enzymatic approach for the synthesis of (2S)-5,5,5-trifluoroleucine and its subsequent resolution into its (2S,4S) and (2S,4R) diastereoisomers. This strategy stands for a sustainable synthesis and enhanced resolution by means of alternative protecting groups for the amino/acid functionalities than that previously reported
