Phototransformation of stilbenes to phenanthrenes via a 6-electron conrotatory electrocyclic ring closure followed by oxidation of a dihyrophenanthrene intermediate is extensively studied as an alternative to multi-step sequences for annelated polycyclic aromatics. Heteroatom analogs of this reaction would result in products potentially applicable as perspective materials for electroluminescent devices, organic conductors and photovoltaic systems.
