## Abstract A novel cyclic dialkyl phosphate was synthesized starting from (+)‐diethyl tartrate. Its catalytic activity as a chiral Brønsted acid has been examined in the Mannich‐type reaction of a ketene silyl acetal with aldimines as a model reaction. The corresponding β‐amino acid esters were ob
