The cyclopentenyl bromides (1) and (9) react with thiophenoxide ion in SN' syn-fasion with very high selectivity.The bromide (4) reacts with the same nucleophile to give the products of SN2 and SN2' syn-reactions.The lactones (1), (4), (15), and (16) react with lithium dibutylcuprate in the SN' anti-fashion predominantly, while the esters (9) and (11) react via the SN' syn-mode preferentially.Mechanisms are presented to explain the substitution patterns observed for the cuprate reactions.
