Expedient and Rapid Synthesis of 1,2,3-Triazolo[5,1-c]morpholines through Palladium-Copper Catalysis

, 2009
A one-pot approach using palladium-copper as catalyst has been developed for the synthesis of morpholines fused with 1,2,3-triazole. Good regioselectivity, mild reaction conditions, high yields and short reaction time are the hallmarks of this ...

Chemoproteomic discovery of a brain‐penetrant, covalent NLRP3 inhibitor that binds a novel allosteric pocket

British Journal of Pharmacology, EarlyView.
NLRP3 is a promising inflammatory target, but existing inhibitors lack diversity and brain penetrance, and none are approved. Using chemoproteomics, we discovered a novel series that binds to Cys463 in a previously uncharacterized pocket. Compounds showed nanomolar potency, brain exposure, and in vivo suppression of IL‐1β, supporting neuroinflammatory ...

Unveiling contrasting iron efficiency strategies in common bean (Phaseolus vulgaris L.) genotypes under iron deficiency

Plant Biology, EarlyView.
Common bean genotypes differ in their iron acquisition through distinct Strategy I responses and root exudation patterns. Abstract Iron (Fe) deficiency in food crops, particularly on calcareous soils, limits productivity and human nutrition. This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe‐accumulating, HI) and ...

Visible‐Light‐Initiated, Nickel‐Catalyzed Aminocarbonylation of Alkynyl Iodides to 2‐Ynamides

Advanced Synthesis &Catalysis, Volume 368, Issue 19, 1 October 2026.
Visible light initiates a nickel‐catalyzed aminocarbonylation of alkynyl iodides, enabling the synthesis of 2‐ynamides under low carbon monoxide pressure. The method operates under mild conditions, tolerates a broad substrate scope, and proceeds through a light‐triggered nickel(I)/nickel(III) carbonylative pathway.

Morpholines, V

Zeitschrift für Naturforschung B, 1972
A new synthesis has been developed for the hitherto unreported 2-substituted-3-oxo-4H-1,4-oxazines 3b-3j via the cyclodehydrohalogenation of N-aryl-N-dichloroacetyl-2-amino-4′-nitroacetophenones in dimethyl sulfoxide with potassium t-butoxide. The structures of all the oxazine derivatives have been verified by IR and NMR spectroscopy and correlations ...

A Blood–Brain Barrier‐Permeable Guanylhydrazone Analogue of the ASIC3 Activator GMQ Inhibits Human Glioblastoma Stem Cell Growth In Vitro

ChemMedChem, Volume 21, Issue 18, 28 September 2026.
The acid‐sensing ion channel 3 (ASIC3), physiologically located in the peripheral nervous system, was found in stem cells of CNS‐located glioblastoma multiforme (GBM CSCs); its chronic activation in the CNS kills dysfunctional GBM CSCs with no effect on ASIC3‐lacking CNS tissues.

Sulfinamides as Highly Effective Amine Protecting Groups and Their Use in the Conversion of Amino Alcohols into Morpholines

, 2011
1,2-Amino alcohols have been converted into morpholines by using sulfinamides as temporary protecting/activating groups on the amine. We have developed a procedure for the selective synthesis of monoprotected N-sulfinyl amino alcohols through a double ...

Lysosome‐Targeted Squaramide Anion Transporters

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Lysosome‐targeted squaramide anion transporters elicit different biological effects depending on the targeting group employed. ABSTRACT Targeting anion transporters to specific organelles has previously been shown to be an effective strategy to enhance their cytotoxicities against cancerous cell lines.
