The reaction of bis(carbene) complexes with bis(alkyne)s in a triple annulation provides direct access to homocalixarenes with three and four aromatic rings. Through proper choice of tether length, these macrocycles were assembled with ring sizes ranging from 15 to 56 carbon atoms. This method allows full control over the ring size and symmetry, and its ability to provide the synthesis of a series of all-homocalixarenes was illustrated for compounds having 2,3,5 and 11 methylene linkers between each ring. This method is also flexible enough to allow the incorporation of a pyrrole unit in place of one of the benzene rings in the calixarene. The macrocycles are always isolated as a single product and can be prepared conveniently on a gram scale. Six of the twelve homocalixarenes that were prepared were characterized by single-crystal x-ray anal.
