摘要
乙二胺四乙酸四钠能有效地催化芳香醛、丙二腈、1-萘酚在体积分数为95%乙醇介质中一锅法合成2-氨基-2-色烯衍生物.该法具有催化剂价廉易得、反应条件温和、实验操作和后处理简便、收率高、催化剂能重复使用等优点.
The synthesis of 2-amino-2-chromenes catalyzed by tetrasodium ethylenediaminetetraacetate (EDTA-4Na) via a one-pot three-component reaction of aromatic aldehyde, malononitrile and 1-naphthol in volume fraction of 95% ethanol has been described. This method offers several advantages such as low cost of the catalyst, mild conditions, good yield, simple experimentaland work-up procedure, and reusability of catalyst.
