3,5-DINITRO-1-(p-NITROPHENYL)-4-PYRIDONE AS A NOVEL PROTECTIVE GROUP OF PRIMARY AMINES
3,5-Dinitro-1-(p-nitrophenyl)-4-pyridone is proposed as a novel protective group for primary amines, especially amino acids, based on the results of the transformation of 1-substituated 3,5-dinitro-4-pyridones with primary amines.
