(¡¾)-2-(4-Chlorophenyl)-2-cyano-2-phenyl-1-hexanol (2) and acetate ester (3) were resolved by various lipases. (R) and (S)-systhane were synthesiaed by the resolved compound 2. The antifungal screening of (R),(S)-systhane and (¡¾)-systhane against wheat leaf rust and barley powdery mildew gave activity over 92% in concentration of 2ppm, but (R)-and (S)-systhane were not more active than (¡¾)-systhane
