Non-superimposable mirror image crystals of both enantiomers(S/R) of cyclicγ-alkenyl alcohol(2) have been recognized and remarkably identified by the naked eye.More interestingly,both crystals are an outcome of most astonishingly H-bond and intermolecularσ/π-πinteractions.They accounted for the relatively rare and less predictable spontaneous resolution with optical purity >99%ee from the racemic mixture.The chiral discrimination mechanism of this spontaneous resolution has also been proposed.
