An enantioselectivedearomatization of isoquinolines has been developed using chiral anion-bindingcatalysis. This transformation, catalyzed by a simple and easy to prepare tert-leucine-based thiourea derivative, makes use of silyl phosphite as a nucleophile and generates cyclic α-aminophosphonates. This is the first time asymmetric anion-bindingcatalysis has been applied to the synthesis of α-aminophosphonates
