Deciphering Cold Stress Resilience: Multiomics Insights in Contrasting Wheat Genotypes From the Western Himalayas

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Merging Micellar Catalysis and C–H Activation: Silver‐Free Direct Arylation of Fluoroarenes in Water

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
We have developed the first silver‐free protocol for a palladium‐catalyzed direct arylation in water under micellar conditions enabling the coupling of diverse pyridine and fluoroarene derivatives. This method combines the sustainability of aqueous media with the efficiency of C–H activation, obviating the need for organic co‐solvents or stoichiometric

Facile Access to N‐Substituted Pyridyl Ligands

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A modular, robust, and versatile Buchwald–Hartwig amination protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine, and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N‐substituents. Pyridyl motifs equipped with N‐substituents can be powerful ligands for catalysis, yet their broader adoption is limited

The stereochemistry of the addition of chlorotitanium enolates of N-acyl oxazolidin-2-ones to 5- and 6- membered N-acyliminium ions

Journal of the Brazilian Chemical Society, 2001
The stereoselective addition of chiral and achiral titanium enolates derived from the corresponding N-acyl oxazolidin-2-ones to 5- and 6- membered N-acyliminium ions afforded 2-substituted pyrrolidines in moderate to good diastereoisomeric ratio (5:1 to ...

Desymmetrization of Pseudo‐para Diformyl[2.2]Paracyclophane via Brønsted Acid‐Catalyzed Reductive Amination

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A highly stereoselective desymmetrization of pseudo‐para diformyl[2.2]paracyclophanes is developed via chiral Brønsted acid‐catalyzed reductive amination. This protocol provides efficient access to enantiopure planar chiral paracyclophanes with broad substrate scope, excellent enantioselectivity, and versatile postsynthetic functionalization. Access to

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...
