convenient one step synthesis of N,N′,N″,N″′-tetra-(2-carboxyethyl)-tetraazacycloalkanes is reported. These compounds are synthesized by Michael addition of tetraazacycloalkanes to acrylic acid. The same Michael addition of tetraazacycloalkanes to an excess of acrylonitrile also leads to the corresponding tetracyanoethylated derivatives. The reduction of such tetracyanoethylated compounds is a new way of preparation
摘要 报道了一种顺利、方便地一步合成 N,N',N",N"'-四-(2-羧乙基)-四氮杂环烷烃的方法。这些化合物是通过四氮杂环烷烃与丙烯酸的迈克尔加成合成的。四氮杂环烷烃与过量丙烯腈的相同迈克尔加成也产生相应的四氰乙基化衍生物。此类四氰乙基化化合物的还原是制备相应伯胺的新途径。
