, p. 7250 - 7252 (2008)
The facile preparation of N(H)-bridged azacalix[4]arenes has been achieved by stepwise nucleophilic aromatic substitutions assisted by hydrogen bonding interactions. The synthesis is uncatalyzed and affords previously unknown tetranitroazacalix[4]arenes.

We describe the synthesis and spectrophotometric studies of novel N(H)-azacalix[4]arenes. The unprecedented direct functionalization of the N(H) bridges furnished N(R)-bridged aza[14]calixarene 11 that could complex a neutral guest (CH2/s
