Aziridination of Cyclic Nitrones Targeting Constrained Iminosugars.
Organic letters(2017)
摘要
Rare C-7-substituted aziridinyl iminosugars can be synthesized through a short reaction sequence involving 1,3-cycloaddition of cyclic nitrones with alkynes and a Baldwin rearrangement of isoxazolines into bicyclic 2-acylaziridines. The method is efficient and completely diastereoselective, producing stable aziridinyl iminosugars in high yields.
