[2++2+2] Cycloisomerisation of Aromatic Cyanodiynes in the Synthesis of Pyridohelicenes and Their Analogues
Original language description
We have developed a methodology for the synthesis of pyridohelicenes and their analogues based on the Ni-0-, Co-I- or Rh-I-mediated intramolecular [2+2+2] cycloisomerisation of cyanodiynes. It allows for folding the linear precursors into the corresponding helical backbones comprising the newly formed pyridine unit in their central part. Along with racemic pyrido[n] helicenes (n = 5,6,7) and their derivatives, both enantio-and diastereomerically pure pyrido[n]helicene-like molecules (n = 5,6) were prepared by employing the chiral substrate-controlled cyclisation of the corresponding enantiopure cyanodiynes.
