  通过甲亚胺酸酯中间体合成单-N-甲基苯胺的简便方法

  摘要：

  已经开发了具有优异产率的制备单-N-甲基苯胺的通用方法。该方案依赖于NaBH 3（OAc）还原的亚甲酸酯中间体，该中间体是通过在MCM-41-SO 3 H中孔沸石的催化下用原甲酸三乙酯处理一级取代苯胺来定量生成的。新开发的程序简便，高效且对环境无害。

  New series of isoniazid hydrazones linked with electron-withdrawing substituents

  摘要：

  A series of new isoniazid hydrazones was synthesized by two procedures. In the first isoniazid was activated with diethoxymethyl acetate and condensed with the appropriate anilines. Alternatively, substituted anilines were activated by diethoxymethyl acetate and subsequently condensed with isoniazid. NMR study confirmed that both synthetic approaches gave the same tautomer. All compounds were screened for in vitro antimycobacterial activity. Most of them exhibited the same activity against Mycobacterium tuberculosis (MIC 1 mu mol L-1) as isoniazid (INH), better activity against Mycobacterium kansasii 325/80 (MIC 0.125-0.250 mu mol L-1), high value of selectivity index (SI) and IC50 between 0.0218 and 0.326 mmol L-1. Compound 2o with the best SI was used as a model compound for the stability test and was found to be stable at neutral pH, but under acidic conditions it slowly hydrolysed.

  日期：2013.7.19

  A multicomponent (single reactor) process for the synthesis of 1-aryl 1,2,4-triazoles was explored and developed. This transformation prepared the 1,2,4-triazole directly from anilines, amino pyridines, and pyrimidines. The reaction scope was explored with 21 different substrates, and the position of the nitrogen atoms in the newly formed ring was established by 15N labeling and NMR spectroscopy.

  The new convenient synthesis of functionalized aryl and pyridyl aminomethylenebisphosphonic acids and their derivatives has been developed via silicon-assisted methodology. New functionalized aminomethylenebisphosphonic acids containing pyridines moieties were obtained using unique reaction of tris(trimethylsilyl) phosphite with N-formyl aminopyridines and trimethylsilyl triflate as a catalyst under

  The desymmetric dicarbofunctionalization of unactivated alkenes by a nickel-catalyzed reductive cross-coupling reaction has been developed to access pyrrolidinones bearing multi-stereocenters with broad functional-group tolerance. The utilization of the 8-Quinox ligand is crucial for maintaining high enantio- and stereoselectivities.
