One‐Pot Synthesis of α‐Amino Phosphonates Using Samarium Diiodide as a Catalyst Precursor

A simple and efficient preparation of α-amino phosphonates under relatively mild conditions by the one-pot reaction of aldehydes with amines and dialkyl phosphites using catalytic amounts of SmI2 is described. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
