A Spiro Phosphamide Catalyzed Enantioselective Proton Transfer of Ylides in a Free Carbene Insertion into N−H Bonds

Free carbene readily causes multiple side reactions due to its high energy, thus its asymmetric transformation is very difficult. We present here our findings of high‐pKa Brønsted acid catalysts that enable free carbene insertion into N−H bonds of amines to prepare chiral α‐amino acid derivatives wi...
