title: Novel imidazolination reaction of alkenes provides an easy access to new alpha,beta-differentiated 1,2-vicinal diamines.
abstract: alpha,beta-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 degrees C without epimerization. Eight examples were examined to give good to excellent yields (87-96%).
