Catalytic Asymmetric Spiroannulation to Access Polycyclic Spiro Enones via Transient Axial-to-Point Chirality Induction and Transfer
Chiral spirocycles exhibit tremendous potential in drug discovery and asymmetric synthesis, owing to their unique three-dimensional rigid framework and superior stability. However, stereoselective construction of polycyclic spiro compounds through a single catalytic transformation remains a significant and enduring cha...
