摘要
Homolytic aromatic substitution reactions are used for the efficient regioselective synthesis of helicenes, phenanthrenes, and azahelicenes. The use of halo and alkoxy substituents to control the stereochemical outcome of this approach and X-ray studies of the resulting helicenes are described (see structure; red O, gray C).
