โฆ Synopsis
A new analgesic, 1-[2-(3-hydroxyphenyl)-l-phenylethyl]-4-(3-methyl-2-butenyl)piperazine (Fig. l), has an asymmetric carbon in the molecule and it has been reported1 that the pharmacological activities of the R(-)-and S(+)-enantiomers were different. It is thus important to examine the optical purity of the enantiomers. P-CH2-CH - HO n P3 .
