High enantioselectivity was achieved for the hydrogenation of azaindoles by using the chiral catalyst, which was prepared from [Ru(η3-methallyl)2(cod)] and a trans-chelating bis(phosphine) ligand (PhTRAP). The dearomative reaction exclusively occurred on the five-membered ring, thus giving the corresponding azaindolines with up to 97:3 enantiomer ratio.

Substituted imidazoles and purine bioisosteres have been widely studied in the literature. We endeavored to combine these heterocyclic core structures into precursors, especially 7-azaindoles, of previously unknown pharmacologically relevant lead structur
