A novel method for the synthesis of 1,3,4-trisubstituted pyrazoles from α-(1,3-dithian-2-yl) enamineketones and primary amines, involving copper(II)-catalyzed oxidative N–N coupling, has been developed. This unprecedented [4+1] approach is versatile in the synthesis of N -aryl, N -benzyl and N -alkyl pyrazoles, and provides an alternative to the conventional [3+2] methods.
