The palladium-catalyzed C-N cross-coupling reaction of diheteroaryl disulfides with heterocyclic amines

The Pd-catalyzed cross-coupling reaction of 1, 2-di(pyrimidin-2-yl) disulfides with heterocyclic amines including 2-amino pyrimidines and 1,3,4-thiadiazol-2-amines to deliver symmetrical C-N coupling products in moderate to good yields is reported. This method provides an opportunity for synthesis of bioactive molecules and pharmaceutically interesting compounds containing heterocycle motifs. The reported protocol shows good functional group compatibility, and provides a new strategy for preparation of C2-amination pyrimidine derivatives from heterocyclic disulfides.
