Abstract:

We report a ligand-free chromium(II)-catalyzed amination reaction of various N-heterocyclic chlorides. CrCl2 regioselectively catalyzes the reaction of chloropyridines and dichloropyridines, dichloroquinolines, dichloroisoquinolines and dichloroquinoxalines with a range of aliphatic, allylic, benzylic and saturated (hetero)cyclic magnesium amides in the presence of lithium chloride as additive. The reactions were performed at 50 °C in THF and led to the desired aminated products in 56–96% yield.

Abstract:

The reaction of 1,4-dichlorophthalazine and 2,3-dichloroquinoxaline with some isoxazolones gave their mono- and bis-isoxazolinyl derivatives. The base-catalyzed rearrangement of these derivatives afforded the corresponding tri- and tetracyclic heterocycles.
