Article Synopsis
- - A new type of bridged azatricyclic ring system, 2-azatricyclo[4.3.2.0]undecane, was successfully synthesized using tricarbonyl(tropone)iron and allylamine through a three-step chemical process.
- - The synthesis steps included an aza-Michael addition, followed by Boc-protection of the resulting secondary amine, and concluded with oxidative demetallation that triggered an intramolecular Diels-Alder reaction.
- - The research also explored how different factors, such as the substitution patterns of the diene and dienophile, as well as the length of the dienophile tether, influenced the outcome of the Diels-Alder reaction.
aza-Michael adducts of tricarbonyl(tropone)iron are synthesized by two different methods. Primary aliphatic amines and cyclic secondary amines participate in a direct aza-Michael reaction with tricarbonyl(tropone)iron under solvent-free conditions. Less nucleophilic aniline derivatives and more hindered secondary amines add efficiently to the cationic tropone complex formed by protonation of tricarbonyl(tropone)iron.
