Abstract: A Mn(III)-catalyzed three-component cascade C-H/N-H functionalization of 2-aminopyridines with 2 equiv of dialkyl butyndioates leads to peri-condensed tricylic azines through a selective, but partly destructive, stoichiometry. A wide range of 2,11-diazatricyclo[5.3.1.04,11]undeca-1(10),4,6,8-tetraen-3-ones were thus obtained with… read more here.
