Abstract A study on the scope of the method to obtain N,N,N′-trisubstituted ethylenediamines III by monoalkylation of N,N′-disubstituted ethylenediamines I through a “one-pot” reaction is presented. It involves condensation of compounds I with aldehydes followed by reduction of the formed imidazolidines II without previous isolation.
摘要 研究了N,N'-二取代乙二胺I单烷基化“一锅法”制备N,N,N'-三取代乙二胺III的方法范围。它涉及化合物 I 与醛的缩合,然后在没有预先分离的情况下还原形成的咪唑烷 II。
