Z-Selective Wittig olefination was applied to thesynthesis of large carbazolophanes containing up to eightheteroaromatic subunits. A number of strategies were devisedand tested, showing that cyclooligomerization yields can besignificantly improved by using one-component schemesinvolving heterobifunctional reactants. [4]- and [6]-Carbazolophanes were characterized in the solid state,revealing compact, highly folded structures. Electronic andsteric effects of substitution and chain length on the Wittig olefination rates andZ-selectivities were explored theoretically usingDFT calculations.
