Regioselective 3-nitration of flavones: A new synthesis of 3-nitro- and 3-aminoflavones
Patoilo, Diana T.,Silva, Artur M. S.,Cavaleiro, Jose A. S.
, p. 1381 - 1385 (2010)
A new, general, and regioselective method for the 3-nitration of flavones have been developed. The nitration reaction is solvent dependent, proceeds via a nitro radical pathway, and the corresponding 3-nitroflavones have been obtained in moderate to very
