New bis-enaminones [(III) and (IX)] are synthesized starting from pyrazoles (I). Their synthetic utilities are successfully demonstrated on the regioselective preparation of novel polyaza-terheterocycles [(V), (VI), (VII), or (X), resp.]. Reaction mechanisms and selectivities are discussed. -(SHAWALI*, A. S.; HABOUB, A. J. M.; J. Heterocycl. Chem. 50 (2013) 1, 17-22, http://dx.
