Irradiation of bicyclic aromatic and aliphatic dienamides in neutral solvent yields a variety of oxazines possessing a spiroheterocyclic framework. The hexatrienic character of these systems is not a prerequisite to their photoannelation but the presence of aromatic units in the parent models strongly modifies their photoreactivity.
