  Novel Approach to 3‐Methyl‐1H‐quinoxalin‐2‐ones

  摘要：

  A novel approach to the synthesis of 3-methyl-1H-quinoxalin-2-ones has been described. These compounds were regioselectively prepared by starting from substituted phenylamines and alpha-chloropropionyl chloride through the efficient procedures of acylation, nitration, reduction, intramolecular alkylation, and oxidation.

  Synthesis and biological evaluation of N4-(hetero)arylsulfonylquinoxalinones as HIV-1 reverse transcriptase inhibitors

  摘要：

  A series of novel N-4-(hetero) arylsulfonylquinoxalinone derivatives were prepared in a straight and efficient way. Of all the synthesized compounds, five compounds exhibited potent anti-HIV-1 replication activities with IC50 value at the level of 10(-7) mol/L. Preliminary structure-activity relationships were studied in details and that will shed light on the discovery of more potent non-nucleoside reverse-transcriptase inhibitors. (c) 2009 Elsevier Ltd.

  A novel catalyst-free cascade amination/cyclization/reduction reaction was developed for the synthesis of various Dihydroquinoxalinones under mild conditions from accessible biomass-derived keto acids and 1,2-phenylenediamines with ammonia borane as a hydrogen donor. This single-step approach enables a simple and eco-friendly route toward the direct synthesis of 12 kinds of Dihydroquinoxalinones in
