Efficient Conjugate Alkylation of α,β-Unsaturated Nitro Olefins by Triorganoalanes

Article abstract of DOI:10.1021/jo00236a012

Both trialkylaluminum (AlR3; R = Et, i-Bu) and triorganoaluminum etherates (AlR3*OEt2; R = Et, i-Bu, Ph) rapidly react with α,β-unsaturated nitro olefins to give only 1,4-monoalkylated products in high yields.The natures of substrates, the reaction conditions as well as the reagents molar ratio, do not cause significant variations on the recovered products.
