Iterative cross-coupling strategy

Approaches to polyaryls 59 + 63 -> 62, DMG = various (Scheme 16) via the DoM - cross coupling strategy can take iterative and convergent forms [58], An illustration of the latter is the construction of a pentaphenyl amide 85 (Scheme 20), of interest as a potential precursor for a macrocyclic host [59].
