Calix[4]arenes fixed in the 1,3-alternate conformation offer an interesting platform for the attachment of further functionalities which has been less frequently used than the cone conformer. Several synthetic strategies were developed to attach four amino functions to the narrow rim, to the wide rim and to both rims of the calix[4]arene fixed in the 1,3-alternate conformation. Using different precursor groups (nitrile/phthalimide or nitro/phthalimide) which can be independently converted into amino functions opens the possibility to attach further groups selectively to the amino functions. Here the groups which is newly attached will determine the reaction sequence.Calix[4]arene des geregelt im wechselnden Angebot der 1.3-Anpassung eine in...
