Enantioselective Dehydrohalogenation Using Chiral Alkoxides: Design of a Catalytic System Allowing Access to Axially Dissymmetric Compounds
摘要:
The use of chiral alkoxides obtained from ephedrines for enantioselective proton abstraction is described in full. These reagents allow the practical obtention of axially dissymmetric 1,3-dioxanes via highly enantioselective dehydrohalogenation reactions. The conditions for a catalytic use of these chiral alkoxides are defined.
