We have found a Tf2O-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.
我们发现了一种由 Tf2O 介导的分子内环化反应,并揭示了在制备中间醇过程中令人感兴趣的立体选择性和区域选择性,从而可以定制合成各种骨架取代的
