无溶剂、无催化剂条件下绿色高效合成N-邻氨芳基-β-烯胺酯

A Green and Efficient Synthesis of N-o-Aminoaryl-β-enamino Esters under Catalyst-free and Solvent-free Conditions

以1,3-二羰基酯和取代的1,2-苯二胺为原料,室温、无溶剂、无催化剂条件下绿色高效合成了9种N-邻氨芳基-β-烯胺酯。该方法不仅产率高、选择性好、反应操作简单,而且还因不使用有机溶剂和催化剂以及反应在室温下进行而具有环境友好、低能耗、清洁高效等优点。

A green, efficient syntheses of nine N-o-aminoaryl-β-enamino esters from 1,3-dicarbony ester and 1, 2-phenylenediamine under catalyst-free and solvent-free conditions at room temperature were reported. The advantages of this procedure were excellent yields of the products, good selectivity, convenient operation, clean and efficient, that is, the procedure is benign to environment and low energy consumption.
