Flipping the Card With Enantiodivergent Organocatalysis
Chemistry – A European Journal, EarlyView.This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

Auxin activity of 3-hydroxymethyl oxindole and 3-methylene oxindole in oat
Biologia Plantarum, 1986 Two photooxidation products of indol-3-ylacetic acid (IAA), 3-hydroxymethyl oxindole (HMO) and 3-methylene oxindole (Meox) were almost as effective as IAA in stimulation of growth of oat (Avena saliva cv. Kent) coleoptile sections. The IAA failed to give stimulation of growth after pretreatment of the coleoptiles with chemicals inhibiting oxidation of ...

Ligand‐Level Chemical Activation: Coordination with Benefits
European Journal of Inorganic Chemistry, EarlyView.While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups

European Journal of Organic Chemistry, EarlyView.Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

Development of the HTRF assay to evaluate the auxin‐induced binding between TIR1 and IAA7
New Phytologist, Volume 250, Issue 5, Page 3475-3485, June 2026.Summary Auxin plays diverse roles in plant growth and development, including sensing environmental changes. Quantifying the interaction between auxin coreceptors provides the molecular basis for cells to sense and adapt to environmental cues. Although several assays are available, a more high‐throughput method is necessary to efficiently evaluate the ...
