A facile and convenient protocol for the reduction of nitro‐arenes and deoxygenation of heteroarenes N‐oxides under transition metal and additive free conditions has been developed. The strategy allows the selective reduction of poly‐nitroarenes as well as the efficient deoxygetaion of a variety of N‐oxides containing heteroarenes including benzofuroxanes and phenzines with a broad substrate scope

Provided are substituted benzaldehydes and derivatives thereof that act as allosteric modulators of hemoglobin, methods and intermediates for their preparation, pharmaceutical compositions comprising the modulators, and methods for their use in treating disorders mediate by hemoglobin and disorders that would benefit from increased tissue oxygenation.
The unexpected substitution of fluorine atoms and phenoxy groups attached to quinoxaline or benzofuroxan rings is described. The synthesis of 2-benzyl- and 2-phenoxy-3-methylquinoxaline 1,4-di-N-oxide derivatives was based on the classical Beirut reaction. The tendency of fluorine atoms linked to quinoxaline or benzofuroxan rings to be replaced by a methoxy group when dissolved in an ammonia saturated
