  Synthesis of New Amphiphilic Dendrons Bearing Aliphatic Hydrocarbon Surface Sectors and a Monocarboxylic or Dicarboxylic Acid Focal Point

  摘要：

  [GRAPHICS]A new series of amphiphilic G1-G3 dendrons containing purely aliphatic hydrocarbon dendritic surface sectors and one or two carboxylic acid group(s) at the focal point was synthesized in good yields. The key branching steps involve diallylation reactions of diethyl malonate or Meldrum's acid. These dendrons are highly soluble in hexane despite having highly polar carboxylic acid groups at the focal point.

  日期：2011.1

  Synthesis of various C‐3‐dialkyl derivatives of quinoline 2,4‐diol was achieved by condensation of aniline or substituted anilines with diethyl malonate, followed by chemoselective alkylation at C‐3 in water. The higher yields, easy work up and environmental compatible conditions are the main aspects of our method. J. Heterocyclic Chem., 2011.
