The first mild, in situ, single-pot, high-yielding well-screened copper (II) salt-based catalyst system utilizing the hydrogen surrogacy of sodium borohydride for selective hydrogenation of a broad range of nitro substrates into the corresponding amine under habitancy of water or methanol like green solvents have been described. Moreover, this catalytic system can also activate various functional groups for hydride reduction within prompted time, with low catalyst-loading, without any requirement of high pressure or molecular hydrogen supply. Notably, this system explores a great potential to substitute expensive traditional hydrogenation methodologies and thus offers a greener and simple hydrogenative strategy in the field of organic synthesis.

Paragraph 0020-0025, (2020/07/21)
The invention provides a novel method for synthesizing 3, 5-dinitrobenzyl chloride. The novel method comprises the following steps: a, carrying out reduction reaction on 3, 5-dinitrobenzoyl chloride and a reducing agent in a first solvent to obtain 3, 5-dinitrobenzene methanol; and b, carrying out chlorination reaction on the 3, 5-dinitrobenzene methanol, a chlorination reagent and a catalyst in asecond solvent to obtain the 3, 5-dinitrobenzyl chloride. According to the method, the reduction process of the 3, 5-dinitrobenzoyl chloride is remarkably improved, a simple reducing agent is used, nitro reduction is avoided under the assistance of Lewis acid and Lewis alkali, and the reaction selectivity and the product yield are improved.

A series of m-amidophenol derivatives (6a-6l, 7a-7q, 9a, 9b, 12a-12c, 14 and 15) were designed and synthesized. Their antitubercular activities were evaluated in vitro against M. tuberculosis strains H37Ra and H37Rv and clinically isolated multidrug-resistant M. tuberculosis strains. Ten compounds displayed minimal inhibitory concentrations (MICs) against M. tuberculosis H37Ra below 2.5 μg mL?1 and 6g was the most active compound (MIC = 0.625 μg mL?1). Compounds 6g and 7a also showed potent inhibitory activity against M. tuberculosis H37Rv (MIC = 0.39 μg mL?1) and several clinically isolated multidrug-resistant M. tuberculosis strains (MIC = 0.39-3.125 μg mL?1). The compounds did not show inhibitory activity against normal Gram-positive and Gram-negative bacteria. They exhibited low cytotoxicity against HepG2 and RAW264.7 cell lines. The results demonstrated m-amidophenol as an attractive scaffold for the development of new antitubercular agents.
