Facile access to amides and hydroxamic acids directly from nitroarenes.
A new method for synthesis of amides and hydroxamic acids from nitroarenes and aldehydes is described. The MnO2 catalyzed thermal deoxygenation of nitrobenzene resulted in formation of a reactive nitroso intermediate which on reaction with aldehydes provided amides and hydroxamic acids. The thermal neat reaction in the presence of 0.01 mmol KOH predominantly led to formation of hydroxamic acid ...
متن کاملPhysiological role of the cyclic hydroxamic acids
Roots of young seedleings of barnyard grass, maize, rye and wheat secret hydroxamic acids. Their compexes with Fe/III/-ions are available sources of iron. It is possible that the cyclic hydroxamic acids play a role in the alternative mechanism of iron uptake. The hydroxamic acids secreted by barnayard grass roots have an allelopathic role by inhibiting the roots growth of rice. Acta Biol Szeged...

Bacteriol. 90:1265-1270. 1965.-The introduction of a hydroxyl group in a number of common barbiturates, a substitution which converts these compounds to cyclic hydroxamic acids, gives rise to compounds which inhibit growth...
متن کاملMicrowave-Assisted Three Component Cyclocondensation Reaction: A Facile Synthesis of Highly Functionalized Cyclohexene Derivatives
Microwave-assisted three component cyclocondensation reactions of aldehydes, amides and dienophiles in the presence of acetic anhydride and para-toluenesulfonic acid as a catalyst to afford the highly substituted cyclohexene derivatives, in relatively good yields after several minutes are reported.
متن کاملTheoretical Studies on Hydroxamic Acids
Hydroxamic acids find many applications in chemistry and biology and have been the subject of many experimental investigations. Theoretical studies are not as frequent. However, the smallest homolog, formohydroxamic acid (FHA), has been studied at various levels, including high-level ab initio and density functional with large basis sets. All studies indicate that it exists as the Z-amide tauto...
