    • Unfortunately, the side product was impossible to separate from the chromanone by chromatography due to identical retention times, independently of elution system used. To isolate the pure product, repeating purification by preparative HPLC is probably required

    • For the cis-isomer, the conformation with the bromine in an axial position and the phenethyl substituent in the equatorial position was favored. The two trans conformations were virtually isoenergetic. For atomic coordinates from B3LYP/LACVP* calculations of the global minimum conformations, see Supporting Information.
