NMR characterisation of photo-electrocyclised structures of a spirooxazine derivative.
Three electrocyclised structures (C-DPh, TTC-DPh and CTC-DPh), produced after UV irradiation of a spirooxazine linked by a (Z)-ethenic bridge to a 2-methoxynaphthalene nucleus, have been identified by NMR spectroscopy.
