Abstract

Resolution of racemic 5-phenyl-2-pentanol via the hemiphthalate ester, followed by diastereomer salt formation with (+)-brucine, separation of the brucine salt of (S)-5-phenyl-2-pentanol hemiphthalate and recovery of the (S)-alcohol therefrom. The (S)-5-phenyl-2-pentanol is a valuable intermediate for organic synthesis.
