Abstract

In this study, the one-pot three-component synthesis of 2-amino-4H-chromenes was accomplished by supramolecular catalysis using a series of well-designed amino-appended β-cyclodextrins (ACDs) in water. The catalytic mechanism was elucidated in detail with 1D and 2D NMR and ESI-MS analyses, while the key roles of amino side chains of ACDs in the reaction chemoselectivity were addressed for the first time.
