An efficient synthesis is described of the substituted azoles referred to in the title, which are precursors of an equally successful new synthetic approach to indoles, benzimidazoles and benzoxazoles. Benzazoles are synthesized almost exclusively by formation of the azole ring on to a benzene nucl
## Abstract Calixpyrroleβbased oligomeric compounds were synthesized by βclick chemistryβ from the corresponding alkyneβ and azideβfunctionalized calix[4]pyrroles. Calix[4]pyrrole **3**, possessing an alkyne functional group, was prepared through a mixed condensation of pyrrole with acetone and but
