Latest Patents

One of Madison's notable patents is for the "Improved synthesis of 1,4,7-triazacyclononane." This patent describes an improved process for obtaining triazacyclononanes, especially 1,4,7-trimethyl-1,4,7-triazacyclononane. The process begins with the reaction of diethylenetriamine (DET) with a sulfonylation agent to form a sulfonamidated DET in an aqueous medium with an inorganic base. In the subsequent step, the sulfonamidated DET aqueous mixture is contacted with an aprotic organic solvent in the presence of a cyclizing unit, resulting in a cyclized sulfonamidated triamine compound. The method emphasizes efficiency by allowing the alkylation of the amine within a single reaction vessel without isolating intermediates. Madison holds 1 patent for this innovative process.
