A highly enantioselective addition of arylboronic acids to cyclic [small alpha]-ketiminophosphonates is reported using chiral palladium phos-phinooxazoline catalyst, providing an efficient and facile route to quaternary [small alpha]-aminophosphonates in high yields and...
A highly enantioselective palladium-catalyzed hydrogenation of a series of linear and cyclic α-iminophosphonates has been achieved, providing efficient access to optically active α-aminophosphonates with up to 99% ee.
