Abstract

A method for the preparation of unsymmetrical urea derivatives that may contain functional groups such as hydroxyl, amine, amide, and carboxyl is described. The method consists of a one-pot modified Curtius rearrangement starting with appropriate aromatic acid chloride and carried out in a nonaqueous system
