Phase-Transfer-Catalyzed Asymmetric Michael Addition of (Iminomethyl)phosphonates to alpha,beta-Unsaturated Ketones: Access to alpha-Aminophosphonic Acid Derivatives
A phase-transfer-catalyzed asymmetric Michael addition of (iminomethyl)phosphonates to alpha,beta-unsaturated ketones is described. In the presence of 1 mol-% of a chiral dinuclear N-spiro ammonium salt, the addition reaction proceeded smoothly to afford the adducts in up to 97 % yield with up to 99:1 dr and 78 % ee. One of the products was readily converted into a cyclic alpha-aminophosphonic acid derivative without any erosion of the enantiopurity.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 538-58-9
