By employing chiral high - performance liquid chromatography , it was possible to follow the time - dependent concentrations of all four isomeric esters ( two regioisomeric pairs of enantiomers ) and all four isomeric alcohols generated during the hydrolysis of enantiopure 1 - ( 4 - chlorophenyl ) - 3 - phenylallyl and 3 - ( 4 - chlorophenyl ) - 1 - phenylallyl 4 - nitrobenzoates .
 Chemical: esters; Chemical: alcohols; Chemical: 1 - ( 4 - chlorophenyl ) - 3 - phenylallyl and 3 - ( 4 - chlorophenyl ) - 1 - phenylallyl 4 - nitrobenzoates
