$({pm})-2-(4-Chlorophenyl)-2-cyano-2-phenyl-1-hexanol$ (2) and acetate ester (3) were resolved by various lipases. (R) and (S)-systhane were synthesized by the resolved compound 2. The antifungal screening of (R), (S)-systhane and $({pm})-systhane$ against wheat leaf rust and barley powdery mildew gave activity over 92% in concentration of 2 ppm, but (R)- and (S)-systhane were not more active than $({pm})-systhane$.
