N-acyl aminocalix[4]arenes were cyclized with nitriles to afford the expected quinazolines only in the case of para-substituted series. This strategy represents a new route to inherently chiral calixarenes potentially useful as fluorescent receptors.

Proximally single-atom bridged calix[4]arenes possess a rigidified cavity and, thus, unusual complexation properties. Here, we report on the synthesis of the first such heteroatom-bridged compound: amine-bridged calix[4]arene. This compound, prepared by thermal decomposition of 4-azidocalix[4]arene, was obtained alongside very interesting rearranged inherently chiral 10H-azepino[1,2-a]indole derivatives. NMR titration confirmed the suitability of amine cavity for the complexation of methylamonnium cations; moreover, the -NH- bridge function enables its further derivatization.
