Triacylamines with Cs symmetry have been explored in asymmetric organocatalysis, leading to the development of a novel catalytic enantioselective desymmetrization of prochiral triacylamines by methanolysis under the catalysis of chiral pseudopeptidic guanidine–guanidinium salt having a weakly coordinating anion. This organocatalytic methodology provides an effective approach to the synthetically useful
