Abstract (±)-2-Cyano-2-phenyl-1-hexanol 3 was resolved to each enantiomer using Candida rugosa and Pseudomonas fluorescens lipases in 62 and 99% ee, respectively. The absolute stereochemistry of one of the enantiomers was determined to be (S) by diastereomeric amide formation and X-ray crystallography. The resolved alcohols of (R)- and (S)-isomer were transformed to Systhane® analogues.
