Helicenes with a substituent exclusively oriented toward the interior curvature of the helix are synthesized by metal-catalyzed cycloisomerization. In addition, novel azulene-fused helicenes have been found through cycloisomerization studies. These helicenes shows a high enough configurationally stability to allow resolution by HPLC on a chiral stationary phase.
