We report the development of a multifunctional reagent for the direct conversion of pyridines to Boc-protected 2-aminopyridines with exquisite site selectivity and chemoselectivity. The novel reagent was prepared on 200-g scale in a single step, reacts in the title reaction under mild conditions without precautions toward air or moisture, and is tolerant of nearly all common functionality. Experimental and in situ spectroscopic monitoring techniques provide detailed insights and unexpected findings for the unique reaction mechanism.

Grubbs catalyst was employed as a new approach to synthesize the 1-azaquinolizinium (pyrido[1,2-a]pyrimidin-5-ium) heterocycle and some simple derivatives. This method was also successfully applied to the first reported synthesis of the benzo-1-azaquinolizinium (pyrimido[2,1-a]isoquinolinium) cation by using the Hoveyda–Grubbs catalyst in Cl2CHCHCl2 at 130 °C.
