General Synthetic Route to Hexaamine Macrocycles
Martin, Andrea E.,Bulkowski, John E.
, p. 415 - 418 (2007/10/02)
A general synthetic route has been developed for the preparation of hexaamine macrocycles containing two diethylenetriamine units joined by aliphatic hydrocarbon bridges of varying length.By use of this method, the new 20-, 22-, and 24-membered polyamines
