aReactions were carried out with 0.1‒0.2 mmol of substrate 1, catalyst 6d (5 mol %), acetic acid (1 equiv.) in toluene at the specified temperature for the specified time. Yields are for the isolated compounds. The enantiomeric ratios (er) were determined by HPLC analysis. bPivalic acid was used instead of acetic acid.
