Abstract :
In this work we present a new way for the direct and general synthesis of urea compounds from primary amines by the modified `phosphine imideʹ reaction. A large panel of amine structures are compatible with the smooth reaction conditions. Particularly in the case of sensitive l-aminoesters, it is interesting to note that the stereochemistry at the asymmetric centre was unmodified in the reaction conditions.
