Abstract
A simple and efficient method for the base-mediated synthesis of unsymmetrical 1,3,5-triazin-2-amines uses readily available imidates, guanidines, and amides or aldehydes as the starting materials and cesium carbonate as the base. This three-component reaction provides diverse 1,3,5-triazin-2-amines in good yields with tolerance of a broad range of functional groups.
