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。
Using 1,3-dicarbonyl ester and substituted 1,2-phenylenediamine as starting materials, nine kinds of N-o-aminoaryl-β-enamines were synthesized in the absence of solvents and catalysts at room temperature. The method not only has the advantages of high yield, good selectivity and simple reaction operation, but also has the advantages of environment friendliness, low energy consumption, high efficiency of cleaning and the like because the organic solvent and the catalyst are not used and the reaction is conducted at room temperature.
