,-Diamino acid derivatives are among the list of most important classes of nitrogen-containing bioactive compounds [1,2]. Their chemistry has attracted lots of focus [3-5], top to discovery and development of quite a few beneficial compounds within the fields of Phospholipase A Inhibitor drug biology, medicine, therapy and food [6-9]. They also belong to useful organic synthetic intermediates as they could be conveniently 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], as well as synthetic fragments for peptides and all-natural products [13]. Mannich-type addition reactions of -amino acid derivatives with imino compounds, or their precursors, is among the most simple synthetic approaches to ,-diamino acid compounds, in certain in asymmetric mode [14-22]. DirectBeilstein J. Org. Chem. 2014, 10, 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 definitely an option methodology [26-28], which tends to make use of ,-unsaturated esters as beginning components to form imidazoline diamine derivatives. Having said that, these methods suffer from the shortcomings, which include have to have of special beginning materials, use of high priced metal catalysts or strict anhydrous and anaerobic conditions. The aminohalogenation reaction has been effectively studied previously decade [29-32], and the corresponding vicinal haloamine item can be quickly converted into aziridines [33,34] and ,dehydroamino acid derivatives [35] within the presence of an organic amine. Not too long ago, we identified that treating haloamine with benzylamine resulted in an unexpected ,-diamino solution, as MMP-1 Inhibitor list opposed to the aziridine or the ,-dehydroamino product. Herein, we report an anomalous outcome within the one-pot reaction, which provides a very efficient strategy for the synthesis of ,-differentiated diamino esters straight from readily readily available beginning materials, ,-unsaturated ester, N,N-dichlorotoluenesulfonamide (TsNCl2) and benzylamine. In addition, the reaction could be carried out within a one-pot model, below operationally easy situations [36-39] by means of Cu-catalyzed aminohalogenation, aziridination and intermolecular S N two nucleophilic ring open.
