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 moderate to high yields in a step-economical fashion under mild conditions

The metal-catalyzed reaction of olefins with allylamines bearing coordination sites (2-pyridyl groups) was studied. With Ru-3(CO)(12) as catalyst, activation of C-H bonds led to the formation of ketimines that were hydrolyzed to give asymmetric ketones. With [(C8H14)(2)RhCl](2), both C-H and C-C bonds were activated and symmetric ketones were formed on hydrolysis. The reaction involves double bond migration of the allylamine to form an aldimine.
