Nitroketeneaminals, V. Synthesis of N2-Substituted 2-Amino-3-nitropyridines as Educts for Pyridopyrazines (3-Deazapteridines)
Mertens, Hubert,Troschuetz, Reinhard
, p. 1143 - 1149 (2007/10/02)
N2-Substituted 2-amino-3-nitropyridines are obtained from the nitroketeneaminals 3 and the 1,3-biselectrophiles 1 and 2.Oxidation and catalytic hydrogenation of 13 yields the 1,2,3,4-tetrahydropyridopyrazine 17.
