Nucleophilic Functionalization of the Calix[6]arene Para- and Meta-Position via p‑Bromodienone Route
It is here demonstrated that the p-bromodienone route,
previously reported for calix[4]arenes, is also effective for the functionalization
of the calix[6]arene macrocycle. Thus, alcoholic O-nucleophiles can be
introduced at the calix[6]arene exo rim. In addition, the reaction of a
calix[6]arene p-bromodienone derivative with an actived aromatic substrate,
such as resorcinol, led to the first example of a meta-functionalized,
inherently chiral calix[6]arene derivativ
