Synthesis and Fungicidal Activity of 1-(Carbamoylmethyl)-2-aryl-3,1-benzoxazines

open access: yesMolecules, 2017
A series of new 1-(carbamoylmethyl)-2-aryl-3,1-benzoxazines were prepared in moderate to good yields by BF3·OEt2-catalyzed reactions of aromatic aldehydes with 2-(N-substituted carbamoylmethylamino)benzyl alcohols.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

Thickness Reduction Strategy for Graphite Composite Bipolar Plates: Materials, Structure, and Manufacturing Process

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
Schematic diagram of challenges and advanced strategies by CBP after thickness reduction. ABSTRACT The proton exchange membrane fuel cell (PEMFC) converts clean hydrogen's chemical energy into electricity and is vital for carbon neutrality. However, its development is limited by low volumetric power density and high cost.
