✦ Synopsis

While numerous cyclophanes exist in which heteroaromatic nuclei (e.g. furan,2-5 thiophene, 296 pyridine 6-8 ) are incorporated into the cyclophane macrocycle, those which contain the pyrrole moiety' are conspicuously absent from these ranks. Recently, we reported the synthesis of a number of cyclophanes containing a single pyrrole nucleus. la We now wish to report the successful completion of the synthesis of the parent unsubetituted nitrogen containing cyclophane, c2.21 (2,5)pyrrolophane (Ia).
