Abstract

α,β-Differentiated 1,2-vicinal diamines have been efficiently synthesized by using new electrophilic imidazolination reaction of alkenes. The hydrolysis of imidazolines was performed by treatment with 6 M HCl in THF at 70 °C without epimerization. Eight examples were examined to give good to excellent yields (87–96%).
