  Efficient one-pot synthesis of β-phosphono malonates and 2-amino-4H-chromen-4-ylphosphonate derivatives by ethylenediamine diacetate-catalyzed three-component reactions

  摘要：

  One-pot three-component reactions of arylaldehyde or salicylaldehyde with malononitrile (or ethyl-cyanoacetate) and triethyl phosphite are carried out in the presence of ethylenediamine diacetate (EDDA) as a catalyst for the synthesis of biologically interesting beta-phosphono malonates and 2-amino-4H-chromen-4-ylphosphonate derivatives. The value of this method lies in its mild reaction catalyst and conditions, good yields, and ease of handling. (C) 2011 Elsevier Ltd. All rights reserved.

  日期：——

  A simple, green and highly efficient approach for the one-pot three-component synthesis of β-phosphonomalonates has been developed. In the presence of the quaternary ammonium salt catalysts, the β-phosphonomalonates were obtained in excellent yields within short times via tandem Knoevenagel–phospha-Michael reaction. The reaction of aldehydes/ketones, active methylene compounds, and diethyl phosphite

  已经开发出一种简单，绿色且高效的方法，用于一锅三组分合成β-膦酰基丙二酸酯。在季铵盐催化剂的存在下，通过Knoevenagel-phospha-Michael反应串联，可在短时间内以优异的产率获得β-膦酰基丙二酸酯。醛/酮，活性亚甲基化合物和亚磷酸二乙酯的反应在室温，无溶剂条件下进行。不需要柱纯化，并且可以通过简单的结晶纯化产物。催化剂可以容易地回收并重复使用几次，而不会显着降低活性。
