Abstractipso-Nitration of t-butyl calixarene tetraethers and subsequent hydrogenation provides an easy access to monoamino calixarenes. Reaction with di- and triacid chlorides leads to various double- and triple-calixarenes. With tetraacid chlorides derived from calixarenes in the cone- or 1,3-alternate-conformations penta-calixarenes are available as molecularly uniform species, which may be regarded as the first generation of calixarene based dendrimers. The structure of the mononitro tetraester derivative, which may serve as a general building block has been confirmed by single crystal X-ray analysis.
