Enabled by nickel catalysis, a mild and general catalytic method for C-alkylation of nitroalkanes with unactivatedalkyliodides is described. Compatible with primary, secondary, and tertiary alkyliodides; and tolerant of a wide range of functional groups, this method allows rapid access to diverse nitroalkanes.

A general catalytic method for asymmetric C-alkylation of nitroalkanes using nickel catalysis is described. This method enables the formation of highly enantioenriched β-nitroamides from readily available α-bromoamides using mild reaction conditions that are compatible with a wide range of functional groups. When combined with subsequent reactions, this method allows access to highly enantioenriched
acrylic esters, obtained by the reaction of nitroalkanes and ethylglyoxalate, are the key building blocks for the immediate synthesis of both the title compounds. In fact, their treatment with titanium trichloride produce the direct conversion to the β-keto esters, while their reaction with sodium boron hydride gives the one-pot synthesis of α,β-unsaturated esters through formal substitution of the
