Enantioselective photoreaction of achiral tropolone ether in inclusion crystals with optically active host compounds.
Achiral 4-isopropyltropolone methyl ether (3) included in an optically active host compound (-)-1 yielded optically active photocyclization products (-)-5 and (-)-6 in 96 and 90% ee, respectively, upon photoirradiation in the solid state.
