Abstract

We have found a Tf(2)O-mediated intramolecular cyclization reaction and have revealed an intriguing stereoselectivity and a regioselectivity during the preparation of intermediate alcohols, which allow for the tailor-made synthesis of various backbone-substituted imidazolinium salts, and structurally specific syn-4,5-disubstituted imidazolinium salts.
