A novel molecular tube fully modified at one end: selective inclusion of cis-unsaturated fatty acid esters.

A novel cyclodextrin molecular tube with one fully modified and one unmodified end was facilely synthesized by selective desilylation of a 6-O-tert-butyldimethylsilylated beta-cyclodextrin dimer possessing multiple linkers. This molecular tube showed a selective inclusion ability toward cis-unsaturated fatty acid esters by utilizing the asymmetric cylindrical nanocavity.
