Graphical Abstract

Abstract

1,2-Diaminocyclohexane-hexanedioic acid has been demonstrated to catalyze the asymmetric aldol reactions of cyclo­ketones and various isatin derivatives efficiently in MeOH–H2O. The corresponding products were obtained in good yields (70–90%) with high diastereoselectivity (up to 99:1 anti/syn) and enantio­selectivity (up to 99% ee).
