Microwave-assistedsynthesis represents a new methodology to obtain calix[6]arenebuildingblocks. 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 upperrim. A conformational
