Abstract: Abstract We developed an efficient method for synthesis of tetrafunctionalized 2-imidazolines using TfOH-catalyzed formal [3+2] cycloaddition of N-tosylaziridine dicarboxylates and nitriles. This is the first report of C–N bond cleavage of N-tosylaziridine dicarboxylates catalyzed by… read more here.
