Synthesis of a new macrocycle as nano machine

A nano machine is an assembly of a discrete number of supramolecular components designed to perform mechanical – like movements as a consequence of appropriate external stimuli. Our purpose is preparation of a part of nano machines are based on interlocked macrocycle named rotaxanes and catenanes. the dibenzisulfide (1) was synthesized by p-cresol and sulfur dichloride in 50% yield. Treatment of (1) with methyl choloroacetat gave dimethyl ester (2) in 98% yiled. Macrocycle (3) in 75% yield was synthesized from reaction of diamidation diester and diethylentriamine. Reaction of compound (3) with sebacoyl dicholoride gave bis azacrown (4).
