,-Diamino acid derivatives are one of the most important classes of nitrogen-containing bioactive compounds [1,2]. Their chemistry has attracted a great deal of attention [3-5], major to discovery and development of several helpful compounds inside the fields of biology, medicine, therapy and meals [6-9]. Additionally they belong to valuable organic synthetic intermediates as they can be effortlessly converted into the corresponding ,-amino alcohols and vicinal diamines. ,-Diamino acid derivatives happen to be served as organocatalysts, chiral ligands, chiral auxiliaries for asymmertric synthesis [10-12], at the same time as synthetic fragments for peptides and organic solutions [13]. Mannich-type addition reactions of -amino acid derivatives with imino compounds, or their precursors, is amongst the most straightforward synthetic approaches to ,-diamino acid compounds, in certain in asymmetric mode [14-22]. DirectBeilstein J. Org. Chem. 2014, ten, 1802807.catalytic oxidative diaminations of functionalized alkenes also present an access for the generation of ,-diamino esters, which generally employ palladium or osmium as catalysts [2325]. The electrophilic diamination reaction is an alternative methodology [26-28], which tends to make use of ,-unsaturated esters as beginning components to kind imidazoline diamine derivatives. Nevertheless, these strategies suffer from the shortcomings, for instance will need of special beginning components, use of expensive metal catalysts or strict anhydrous and anaerobic situations. The aminohalogenation reaction has been effectively studied previously decade [29-32], and also the corresponding vicinal haloamine item is usually easily converted into aziridines [33,34] and ,dehydroamino acid derivatives [35] in the presence of an organic amine. Not too long ago, we found that treating haloamine with benzylamine resulted in an unexpected ,-diamino solution, rather than the aziridine or the ,-dehydroamino item. Herein, we report an anomalous outcome in the one-pot reaction, which supplies a hugely effective method for the synthesis of ,-differentiated diamino esters straight from readily accessible beginning materials, ,-unsaturated ester, N,Met Inhibitor Gene ID N-dichlorotoluenesulfonamide (TsNCl2) and benzylamine. Furthermore, the reaction could be performed within a one-pot model, beneath operationally convenient conditions [36-39] via Cu-catalyzed aminohalogenation, aziridination and intermolecular S N two nucleophilic ring open.
