The reactions of ketene dithioacetals with ethane-1,2-diamine, propane-1,3-diamine, 2-aminoethanol, 3-aminopropanol, and 2-aminoethanethiol in ordinary water in the absence of any acid/base catalyst afforded the heterocyclic ketene N,N-, N,O- and N,S-acetals in good yields.
在没有任何酸/碱催化剂的情况下,乙烯酮二硫缩醛与乙烷-1,2-二胺、丙烷-1,3-二胺、2-氨基乙醇、3-氨基丙醇和2-氨基乙硫醇在普通水中反应得到杂环乙烯酮N,N-、N,O- 和 N,S-缩醛的收率良好。
