Abstract
A one-pot multicomponent carbonylation/amination sequence enables a convenient synthesis of N-acylguanidines. A formation of an N-cyanobenzamide intermediate from the Pd(0)-catalyzed carbonylative coupling of cyanamide and aryl iodides or bromides is followed by amination with various amines to provide the final N-acylguanidines in good yields. Furthermore, various heterocycles were prepared from the N-acylguanidines.
