Tryptycene-derived macrotricyclic

A series of tryptycene-derived homooxacalixarenes (6) was conveniently prepared by a one-pot approach starting from 2,7-dihydroxytriptycene and l,3-bis(bromomethyl)benzene derivatives under mild conditions (13JOC981).Tryptycene-derived macrotricyclic polyethers containing two dibenzo [30] crown-10 cavities and different functionalized paraquat derivatives, diquat, and a 2,7-diazapyrenium salt in both the solid state and in solution were studied (13JOC3235). The first organometallic (Pd) complexes of an oxacalixarene were prepared by oxidative addition of the C-I bond on the lower rim (13IC6779).
