An umpolung reaction of α-tosyloximino esters in a flow system is disclosed. Tandem N, N-dialkylations with two different Grignard reagents gave the desired N, N-dialkylated products in moderate to good yields. In addition, a tandem N, N, C-trialkylation of an α-tosyloximino ester with three different Grignard reagents has been successfully achieved to afford the desired N, N, C-trialkylated product in moderate yield.

α-N-Acyloxyimino esters serve as highly efficient substrates for the N,N,C-trialkylation reaction that can introduce various patterns of nucleophiles at the imino nitrogen and carbon atoms to synthesize N,N-dialkylated and N,N,C-trialkylated α-amino esters in moderate to high yields.

N,N-Dialkylation of α-sulfoximino esters with Grignard reagents proceeds to give α-N,N-dialkylamino esters. N,N,CTrialkylated product is also obtained via the oxidation and nucleophilic addition reaction of the intermediary enolate.

The complexes TpXCu (TpX = homoscorpionate) catalyse the insertion of diazo compounds into nitrogen-hydrogen bonds of amines and amides, under very mild conditions, with quantitative yields being obtained with equimolar ratios of reactants.
The Chemistry of N-Substituted Benzotriazoles Part 23. Synthesis of Tertiary α-Amino Esters

, p. 323 - 327 (2007/10/02)
2-Dialkylaminoalkanoic esters 6 are prepared in good yield by the reaction of organozinc derivatives 5 with dialkylamino(1-benzotriazolyl)acetic esters 4, obtained from the condensation of secondary amines 3 with ethyl glyoxylate 2 and benzotriazole 1.
