7-氧杂双环[2.2.1)-庚-5-烯-2,3-二酰亚胺的N-烃基衍生物是一类有生物活性的化合物。刘纪云等用相应的酸酐和各种胺类化合物在水或醇中反应合成了上述化合物,但收率较低。聚乙二醇(PEG)作为一种新的相转移催化剂在合成中广有应用。实验证明PEG
N-Hydrocarbyl derivatives of 7-oxabicyclo [2.2.1] -hept-5-ene-2,3-diimide are a class of biologically active compounds. Liu Ji-Yun and other corresponding anhydrides and various amines in water or alcohol synthesis of the above compounds, but the yield is low. As a new phase transfer catalyst, polyethylene glycol (PEG) is widely used in the synthesis. Experimental proof PEG
