Mild and Metal-Free Regioselective 1,2-Addition of Carbon Nucleophiles to α,β-Unsaturated Imines.

A mild and metal-free regioselective 1,2-addition of carbon nucleophiles to α,β-unsaturated imines has been developed. Good yields and total regioselectivities were achieved by addition of p-nitrobenzyl chloride or 2,3-bis(bromomethyl)quinoxaline to α,β-unsaturated tosylimines.
