Enantioselective Synthesis of Chiral Amides by Phosphoric Acid-Catalyzed Asymmetric Wolff Rearrangement [PDF]
The enantioselective addition of potent nucleophilic reagents to ketene compounds poses challenges due to the presence of significant background reactions, along with simultaneous stereoselectivity and enantioselectivity issues in the reaction process ...
