    • 10 studies were performed to confirm the structure of these chiral sensitizing hosts. The solubility of these hosts were poor in general in pure water, but were considerably improved by adding 5-50% methanol to the aqueous solutions

    • General procedure for photolysis: Aqueous methanol solutions (5 mL) containing 1Z (1.5 mM) and modified cyclodextrin (0.05-0.15 mM, determined by the solubility) were irradiated at 254 nm in quartz tubes under an argon atmosphere at temperatures -5 °C by using a ultraviolet lamp (TUV PL-L 60 W) from Philips. Each photolyzed sample was poured into a 10% aqueous KOH solution (5 mL), and the resulting mixture was extracted with pentane (1 mL). The organic extract was analyzed by gas chromatography on a Supelco BETA-DEX™ 225 column for both the E/Z ratio and ee of 1E
