Hot Article: multirotaxanes molecular shuttles

While a relatively large number of [2]-rotaxanes, in which a ring is threaded by an axle, have been reported in the literature, [3]-rotaxanes (where two macrocyclic rings are able to move along the axis on which they are threaded in a controlled fashion) and [4]-rotaxanes (where 3 macrocycles are threaded on the axle) still prove a real synthetic challenge.

In this NJC Letter, the group of J.-P. Sauvage (Strasbourg, France) provide insights on the successful preparation of multirotaxanes, and synthesize a [2]-, a [3]- and a [4]-rotaxane in the same reaction.
