Synthesis of Substituted Cyclic Amines From Protected Amino Acids Using Oxidative Decarboxylation and Alkylation

Asian Journal of Organic Chemistry, Volume 15, Issue 2, February 2026.
Simple access to alkylated 3D scaffold via oxidative radical decarboxylation, trapping of iminium, and successive reaction with organometallic reagent in the presence of BF3 . ABSTRACT Cyclic amines are vital scaffolds in bioactive molecules and drug discovery, often functionalized via electrochemical Shono‐type oxidation to access N‐acyliminium ...

Further Insights Into the Metabolism of LGD‐4033 in Human Urine. Part 1. Structure Elucidation of Additional Important Metabolites

Drug Testing and Analysis, Volume 18, Issue 2, Page 245-259, February 2026.
Well‐characterized, chemically synthesized molecules related to LGD‐4033 metabolism were used as analytical standards for the analysis of LGD‐4033 post‐administration urine samples. This approach offered further insights into LGD‐4033 metabolism, providing solid experimental proof for the structure of important previously reported metabolites and ...

Exploring the Controllability of Microbial Metabolism on the Flavor of Chinese Baijiu

eFood, Volume 7, Issue 1, February 2026.
Regulation of flavor compounds by core functional microorganisms. ABSTRACT The flavor and quality of Baijiu are closely related to the environment and microbial metabolism. The microbial community structure is highly dynamic in time and space, making it trouble to control the flavor and quality of Baijiu. Therefore, this paper reviewed the role of core

Acid‐Promoted ROMP of a Pyridine‐Fused Norbornene Toward Main‐Chain Cationic Polymers

Macromolecular Chemistry and Physics, Volume 227, Issue 3, 16 February 2026.
Cationic polymers are valuable materials for applications ranging from biomedicine to ion transport. We report the ROMP of pyrido[2,3‐b]norbornadiene, a pyridine‐fused norbornene monomer, under acidic conditions. Protonation with HCl suppresses deleterious pyridine–Ru coordination, enabling controlled polymerization to afford well‐defined polymers with

Structure Elucidation of Biflavones With Ether Bonds by NMR‐Spectroscopy—Structure Revisions of Loniflavone and Methylloniflavone

Magnetic Resonance in Chemistry, Volume 64, Issue 2, Page 165-169, February 2026.
The structures of the biflavones loniflavone and methylloniflavone from Lonicera japonica have to be revised to ochnaflavone and methylloniflavone based on two NMR approaches without derivatization. ABSTRACT For the structure elucidation of biflavones in which the subunits are linked by an ether bridge, two NMR spectroscopic approaches are shown to ...
