Internal Chelation-Guided Regio- and Stereoselective Pauson-Khand-Type Reaction by Chiral Rhodium(I) Catalysis

Touch, Pauson, engage: To explain the unique superior reactivity and stereoselectivity of O‐tethered enynes in asymmetric Pauson–Khand type reaction (APKR) than their congeners, the internal‐chelation to metal of oxygen atom of the substrate in the transition state was proposed. This proposition was...

Zusammenfassung:	Touch, Pauson, engage: To explain the unique superior reactivity and stereoselectivity of O‐tethered enynes in asymmetric Pauson–Khand type reaction (APKR) than their congeners, the internal‐chelation to metal of oxygen atom of the substrate in the transition state was proposed. This proposition was well supported by APKR with several different substrates.
