, (2013/02/28)
The present invention relates to substituted heteroaromatic dianlamine compounds of Formula I and II, their pharmaceutically acceptable salts, and compositions thereof useful as antioxidants, wherein each of X, Y and Z are independently a carbon or nitrogen atom; R1 and R2 are each independently a hydrogen or an electron donating group, but are not both hydrogen, and wherein R1 and R2 are each bonded to a carbon atom in their own respective aryl ring.

(Chemical Equation Presented) A convenient approach to 3-pyridinols and 5-pyrimidinols via a two-step Cu-catalyzed benzyloxylation/catalytic hydrogenation sequence is presented. The corresponding 3-pyridinamines and 5-pyrimidinamines can be prepared in an analogous sequence utilizing benzylamine in lieu of benzyl alcohol. The radical-scavenging ability of these derivatives are preliminarily explored and reveal that the increased acidities of the pyridinols and pyrimidinols render them susceptible to more significant kinetic solvent effects when compared to phenols.
