macrocycles of interest in the
preparation of optoelectronic and porous materials. New cyclotetrabenzoins
derived from biphenyl, naphthalene, and tolane skeletons were synthesized
using N-heterocyclic carbene-catalyzed benzoin condensation.
Their preparation proceeded with different regioselectivity than that
observed in the cyanide-catalyzed preparation of the parent cyclotetrabenzoin.
Crystal structures of two new cyclotetrabenzoin acetic esters have
been obtained. Alkyne groups of the tolane-based cyclotetrabenzoin
were postsynthetically functionalized with Co2(CO)6 moieties.
