Ceria–Zirconia-Supported Pt as an Efficient Catalyst for the Sustainable Synthesis of Hydroxylamines and Primary Amines via the Hydrogenation of Oximes Under Ambient Conditions

Molecules
Amines and hydroxylamines are essential compounds in the synthesis of pharmaceuticals and other functionalized molecules. However, the synthesis of primary amines and particularly hydroxylamines remains a challenging task.

NMR‐Based Structural Analysis of Highly Substituted Pyridines From Kondrat'eva Aza‐Diels–Alder Cycloadditions

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 324-332, March 2026.
We report the results from a kinetic and mechanistic investigation of an inverse‐electron‐demand Diels–Alder (IEDDA) cycloaddition involving an oxazole‐type diene synthesized via an Ugi–Zhu multicomponent reaction (UZ‐3CR). ABSTRACT Pyridines are a crucial class of heterocycles with widespread applications in natural products, pharmaceuticals, and ...

Genome‐wide association study identifies consistent genomic loci for yield and nutritional quality in Ethiopian sorghum landraces

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Identifying genomic regions linked to yield and quality is crucial for sorghum (Sorghum bicolor L.) improvement, but limited studies on its genome and diversity hinder breeding efforts. This study aimed to identify phenotypic variance and common quantitative trait nucleotides (QTNs) associated with genomic regions linked with grain yield and ...

Strain‐Release Diversification of 1‐Azabicyclobutanes via Bromide/Nickel Relay Catalyzed 1,3‐Bis‐Carbofunctionalization

Angewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
A four‐component synthesis of azetidines with an all‐carbon quaternary center via strain‐release 1,3‐bis‐carbofunctionalization of 1‐azabicyclobutanes (ABB) is described. Each reaction component can be modified to permit a high‐throughput‐like library preparation, producing azetidines with various appendages, including biorelevant molecules.

Organophosphate Poisoning: Review of Prognosis and Management

Advanced Biomedical Research
The high annual mortality rate of organophosphorus (OP) poisoning indicates that the treatment is mostly ineffective in this regard. It has been suggested to add calcium channel blocking (CCB) drugs or magnesium sulfate (MgSO4) to normal care to decrease
