Enantioselective assembly of chiral acyclic sulfonimidamides via carbene-catalyzed desymmetric N-acylation
摘要
Sulfonimidamides play an increasingly significant role in medicinal chemistry. However, the scarcity of efficient asymmetric methods has constrained their widespread applications. Herein, we report a simplified carbene-catalyzed N-acylation approach for the rapid synthesis of chiral unprotected acyclic SIAs. This transformation proceeds via a critical tautomerization process, affording a wide range of SIAs in good yield and with high enantioselectivities.
