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.
