Application

4-Methyl-3,5-dinitrobenzoic acid was used in characterization of the range of highly polar nitroaromatic compounds in water samples from a trinitrotoluene-contaminated waste disposal site. It was used as starting reagent for the asymmetric synthesis of the benzazocine core of FR900482.

Leachate and ground water samples from a trinitrotoluene-contaminated waste disposal site near a former ammunitions plant in Stadtallendorf, Germany, were analyzed by liquid chromatography (LC)-mass spectrometry (MS) and LC-NMR hyphenated techniques to comprehensively characterize the range of highly polar nitroaromatic

An asymmetric synthesis of the benzazocine core of FR900482 has been achieved in 15 steps from 3,5-dinitro-p-toluic acid. Key features of the synthesis include an enantioselective N-methylephedrine-mediated zinc acetylide addition to a highly enolizable arylacetaldehyde and a novel Pd-catalyzed carbonylative
