Synthesis of hydroquinone-, biphenol-, and binaphthol-containing aza macroheterocycles via regioselective hydroformylation and reductive amination

Rhodium(I) catalyzed regioselective hydroformylation of diolefins and subsequent reductive amination of the dialdehydes in the presence of α,ω-diamines is applied to azamacroheterocyclic ring synthesis. Starting from aromatic diallyl ethers of hydroquinone, biphenol and binaphthol 20-28 membered macroheterocycles were obtained in up to 78% yield.
