Reduction of α,β-unsaturated nitroolefins into nitroalkanes with Hantzsch ester promoted by isothiouronium salts.

α,β-Unsaturated nitroolefins were reduced into nitroalkanes with a Hantzsch ester, promoted by S-benzyl isothiouronium iodide. The reactions proceeded successfully to afford the desired products in high yields and with excellent chemoselectivity. [ABSTRACT FROM AUTHOR]
