Multiple Absolute Stereocontrol in Cascade Lactone Formation via Dynamic Kinetic Resolution Driven by the Asymmetric Transfer Hydrogenation of Keto Acids with Oxo-Tethered Ruthenium Catalysts
straightforward asymmetric construction of chiral fused γ- and δ-lactones containing multiple contiguousstereocenters was successfully developed by either (1) the dynamic kinetic resolution-asymmetric transfer hydrogenation (DKR-ATH) reaction using oxo-tethered Ru(II) complexes followed by syn-selective lactonization or (2) the tandem DKR-ATH/lactonization in combination with asymmetric hydrogenation
