2-(N-tert-butoxycarbonylamino) pyridine and 2-(N-tert-butoxycarbonylamino)-3-methylpyridine were synthesized in a one-step method using either 2-aminopyridine or 2-amino-3-methyphyridine with tert-butylcarbonyl anhydride as the starting materials. The products were characterized by single-crystal X-ray diffraction, 1H NMR, 13C NMR, and HRMS. The biological activity of the two compounds against five fungi was determined. 2-(N-tert-butoxycarbonylamino) pyridine has more than 50% inhibitory activity against Pyricularia oryzae, Colletotrichum gloeosporioides, and Alternaria alternate. In addition, the inhibitory activity of 2-(N-tert-butoxycarbonylamino)-3-methylpyridine against Alternaria alternate reached 67.69%. Two 2-BOC aminopyridine derivatives were synthesized and structurally characterized by 1H NMR, 13C NMR, HRMS analysis and X-ray crystal diffraction. The inhibitory activity both compounds was studied. [ABSTRACT FROM AUTHOR]
