Intramolecular meta-arene alkene photocycloaddition of 1b, the substrate having a chiral auxiliary as a linking bridge between the arene and the alkene, resulted in high diastereofacial differentiation of the alkene at the addition step and sufficient regiocontrol of the subsequent ring closure step to give a single diastereomer 4.
