We report a H3PO3/I2 mediated formation of N-benzyl benzo heterocyclic ketones from the reaction of benzo heterocyclic compounds with aromatic aldehydes or benzyl alcohol derivatives under metal-free conditions in one-pot. For the first time, aromatic aldehydes were used as benzylated reagents to synthesize benzo heterocyclic ketones in the presence of K2CO3. Control experiments indicated that the
我们报告了 H 3 PO 3 /I 2介导的N-苄基苯并杂环酮的形成,该反应由苯并杂环化合物与芳香醛或苯甲醇衍生物在无金属条件下在一锅中反应。首次以芳香醛为苄基化试剂在K 2 CO 3存在下合成苯并杂环酮。对照实验表明羰基氧最有可能来源于K 2 CO 3。H 3 PO 3还起到促进剂和氢源的双重作用。这种新方法具有底物范围广、成本低、条件简单等特点。

The cytokine MIF is involved in inflammation and cell proliferation via pathways initiated by its binding to the transmembrane receptor CD74. MIF also exhibits keto-enol tautomerase activity, believed to be vestigial in mammals. Starting from a 1 mu M hit from virtual screening, substituted benzoxazol-2-ones have been discovered as antagonists with IC50 values as low as 7.5 nM in a tautomerase assay and 80 nM in a MIF-CD74 binding assay. Additional studies for one of the potent inhibitors demonstrated that it is not a covalent inhibitor of MIF and that it attenuates MIF-dependent ERK1/2 phosphorylation in human synovial fibroblasts.
