All possible stereoisomers of cis- and trans-2-fluorocyclopentan-1-ols were obtained by kinetically controlled deracemization in the presence of lipases in organic media. High enantioselectivities and good yields of stereomers were obtained for all substrates. Optically pure 1,2-fluorocyclopentan-1-ols were converted to 2-fluoro-cyclopentan-1-amines using the Mitsunobu reaction. The absolute configurations were determined using the Kazlauskas rule and chemical correlation. The interaction of substrates with enzymes has considered using Koshland induced fit theory.
