Recently I am researching about SELECTIVE SYNTHESIS; PENTAARYLPYRIDINES; ARYLPYRIDINES; CONSTRUCTION; CONDENSATION; DERIVATIVES; ENAMINES; KINETICS; BINDING, Saw an article supported by the . HPLC of Formula: C8H7NO3. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Arita, M; Yokoyama, S; Asahara, H; Nishiwaki, N. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
Condensation of beta-(2-pyridyl)enamine and alpha,beta-unsaturated ketone in the presence of FeCl3 under air afforded highly substituted pyridines. In this transformation, FeCl3 acted as not only an acid catalyst but also an oxidant for the intermediate dihydropyridine. The substituents could be easily modified by altering the substrates to obtain tri- and tetraarylpyridines including bipyridines and terpyridine. Synthesis of differently substituted pentaarylpyridines was consequently achieved via only three steps from commercially available reagents with simple experimental manipulations.
