Microwave‐assisted synthesis represents a new methodology to obtain calix[6]arene building blocks. The synthesis of compounds 1 and 2 is described. These compounds are A,D‐ m ‐xylylenedioxy‐bridged calix[6]arenes in cone conformation, functionalized with potential amino groups in the lower rim spacer (5‐position) and amino groups or their precursors in A,D‐ para positions at the upper rim. A conformational study has been performed for all newly synthesized compounds.
