Just plain chiral: The [7]orthocyclophanes 1, having an E-olefinic ansa chain, exhibit planar chirality at ambient temperature and their stereochemical stabilities are highly dependent upon the embedded X group in the ansa chain. Inter- and intramolecular transformations of 1 (where X=NTs) provide a variety of nitrogen-containing chiral molecules in a stereospecific manner. Ts=4-toluenesulfonyl. Copyright
