American Journal of Botany, EarlyView.Abstract Premise Human activity has significantly altered the salt cycle, affecting an estimated 2.5 billion acres of soil worldwide. Elevated soil salinity is a well‐known plant stressor, but it may also affect interactions between plants and insects, which are often sodium limited.

Angewandte Chemie, EarlyView.Enantioselective aminoarylation of ortho‐allyl anilines is achieved under mild conditions. Key to success is the electrostatically‐directed nature of the key aminopalladation step, achieved by using the sulfonated chiral ligand sSPhos on palladium. A detailed study of electronic trends allows tuning of the sulfonamide protecting group to enable good ...

Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation
Angewandte Chemie, EarlyView.Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts.

Towards continuous deracemization via racemic crystal transformation monitored by in-situ Raman spectroscopy [PDF]
, 2019 In this work, we demonstrate a semi-batch solid-state deracemization process for N-(2- chlorobenzylidene)-phenylglycine amide (NCPA), a complex chiral polymorphic system that involves three types of crystalline racemates (racemic compound and ...
