A new helically chiral pentacyclic phosphine, containing one thiophene ring, was prepared in good yield and purity via a five-step sequence involving a Wittig reaction, a palladium-catalyzed Mizoroki-Heck coupling, and classical oxidative photocyclization reactions. The investigation using ultraviolet-visible spectroscopy shows that the helicene precursor of the target helical phosphine as well as its phosphine oxide have interesting behaviors.
