Synthesis of the first [34]allenophane: 1,3,10,12,19,21,28,30- octamethyl-[3.3.3.3]paracyclophan-1,2,10,11,19,20,28,29-octaene

A 'true' allenophane with several rings and allenic bridges was synthesized. The key step in the preparation of 1 was the cyclization to a 28-membered macrocycle (52 % yield) starting from a linear molecule, which already contains three of the four allene
