Using the recently introduced trapping method based on the reaction of nucleophilic organic anion-macrolactam complexes with electrophilic building blocks, a series of new rotaxanes was synthesized upon formation of sulfide, N-tosylamide, thioester and phosphate bonds. The yields are high (41-88%) which underlines the versatility of the new synthetic concept.
