摘要
[8](2,5)Heterocyclophanes 2a-c have been obtained by means of Paal-Knorr synthesis applied to 1,4-cyclododecanedione (1). N-Substituted pyrrolophanes (2d, e and 3a-d) also have been prepared from 1 and primary amines. In addition, a novel type of ansa compounds 5a-c were obtained from 1 and p-phenylenediamine derivatives. Conformations of these compounds are discussed on the basis of UV and NMR spectra. © 1969.
