    • Following reviewers' suggestions, under the optimized reaction conditions, the efficiency of other acid cocata-lysts such as CF 3CO2H [pKa, 0.52, 8 h, 5% conversion, untilsyn: nd, 92% ee (and, and C12CHCO2H [pKa, 1.35, 8 h, 16% conversion, antilsyn: 98/2, 89% ee anti, was also checked affording high enantioselectivities but very low conversions. Thus, in terms of conversion and enantioselectivity, 4-NO2C6H4CO2H [8 h, 99% conversion, antilsyn: 94/6, 95% ee {and, was definitively recognized as the best cocatalyst for the aldol reaction
    • 2H [8 h, 99% conversion, antilsyn: 94/6, 95% ee {and)] was definitively recognized as the best cocatalyst for the aldol reaction.
