Metathesis with a twist! A ring‐closing‐metathesis strategy has been developed for the preparation of various substituted [5]helicene motifs and [6]‐ and [7]helicenes. The two optimized protocols include one method that utilizes the Grubbs second‐generation catalyst under microwave‐irradiation conditions and another that employs a modified Grubbs–Hoveyda catalyst at 40 °C in a sealed reaction vessel.
