    • The enantiomeric excesses of the alcohols derived from acetophenone, propiophenone, and butyrophenone were also estimated by HPLC analysis of the corresponding 3,5‐dinitrobenzoates on a covalent D‐naphthylalanine column (Regis Pirkle, length 25 cm × 4.6 mm) using 2‐propanol/hexane (1/500) mixture as the mobile phase (flow rate: 1.0 mL/min), The retention times for the 3,5‐dinitrobenzoates for the alcohols are listed below: (S)‐(‐)‐1‐phenylethanol, 43.02 min; (R)‐(+)‐1‐phenylethanol, 44.16 min; (S)‐(‐)‐1‐phenylpropanol, 36.67 min; (R)‐(+)‐1‐phenylpropanol, 38.18 min; (S)‐(‐)‐1‐phenylbutanol, 32.45 min; (R)‐(+)‐1‐phenylbutanol, 33.80 min. UV detector was monitored at 254 nm.

    • In the presence of ethanol, the same general procedure as that described in the Experimental section was followed except with the addition of ethanol.
