摘要 首先采用汇聚法合成了树枝状大分子羧酸;树枝状大分子羧酸与修饰的DPEN连接后,脱去保护基得到了两个新型手性树枝状二胺配体(4和9)。当以铑络合物(Rh-4或Rh-9)为催化剂,以甲酸钠为氢源,进行水相中芳香酮的不对称转移氢化反应时,Rh-4显示了较高的催化活性。 Dendritic carboxylic acid was synthesized via convergent approach. The dendritic carboxylic acid was attached to modified DPEN, and dendritic ligands(4 and 9) were synthesised after cleavage of protective group. With Rh complex( Rh-4 or Rh-9) as catalyst and HCO2Na · 2H2Oas hydrogen source, highly efficient asymmetric transfer hydrogenation of aromatic ketone in water was achieved.
