Asymmetric Synthesis of Tertiary α‐Aryl Stereocentres in Tetrahydro‐4H‐pyran‐4‐ones Using Pd‐Catalyzed Decarboxylative Asymmetric Protonation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The Pd‐catalyzed decarboxylative asymmetric protonation (DAP) has been developed for sterically hindered tetrahydro‐4H‐pyran‐4‐one derived α‐aryl‐β‐keto esters. A substrate scope of nine examples of DAP showed that substrates containing a di‐ortho methoxy substitution pattern on the aryl ring gave rise to the highest enantioselectivities of up to 85 ...

Coated and Immobilized Polysaccharides‐Based Stationary Phases for Planar Metallocenes Enantioseparation in Liquid Chromatography

open access: yesELECTROPHORESIS, EarlyView.
This study examined 21 new ferrocene and ruthenocene derivatives, including those with planar and central chirality. Their stereochemical behavior was examined using UV‐detected normal‐phase liquid chromatography. Under fixed conditions, eight polysaccharide‐based chiral stationary phases were tested using n‐heptane combined with either 2‐propanol or ...
