Article Abstract
A three-component reaction of trifluoromethyl enones, phosphine oxides, and alcohols in water solution is developed. This defluorinative reaction occurs through a cascade process involving defluorophosphorylation, defluoroalkyloxylation, and defluoroheteroannulation, enabling the modular synthesis of furans with four distinct substituents: 2-alkyloxy, 3-trifluoromethyl, 4-phosphoryl, and 5-(hetero)aryl groups. Moreover, apart from alcohol substrates, the scope of nucleophiles could be further extended to phenols, azacycles, or sulfonamide.

An early surge of norepinephrine along brainstem pathways drives sensory-evoked awakening.

The locus coeruleus-norepinephrine (LC-NE) system regulates arousal and awakening; however, it remains unclear whether the LC does this in a global or circuit-specific manner. We hypothesized that sensory-evoked awakenings are predominantly regulated by specific LC-NE efferent pathways. Anatomical, physiological, and functional modularities of LC-NE pathways involving the mouse basal forebrain (BF) and pontine reticular nucleus (PRN) were tested.

Zinc(II) bis(triazolyl)(pyridyl)amine (Zn(BTPA)) complexes on the end of α-amino-iso-butyric acid (Aib) foldamers are able to transfer chirality from bound anions to the helical foldamer body. Zn(BTPA) could be obtained by simple synthetic methodology that allowed a range of functional groups to be installed around the binding site, exemplified with a fluorophore, a macrocyclic bridge and Aib itself. Changing functional group did not prevent chiral ligands from controlling foldamer conformation, although differences in complexation kinetics and equilibria were observed.

[2,1]-Azaboranaphthalenes represent unique boron-nitrogen (BN) isosteres of naphthalenes, attracting interest for the development of molecules with enhanced therapeutic potency. The existing synthetic strategies are generally two-component reactions with harsh conditions. Here we report an organocatalysed three-component modular synthesis of ring-fused BN isosteres and BN-2,1-azaboranaphthalenes following ring expansion of unstrained cyclic ketones (n = 4-8) via Wolff-type rearrangement.

A series of unsymmetrically substituted BODIPY dyes featuring fused benzo- or naphtho-fragments on one pyrrolic unit were synthesized from the corresponding pyrrolic precursors. The synthetic route was optimized using a modular approach based on the condensation of formylpyrroles with alkylpyrroles, enabling the identification of precursor combinations that minimize byproduct formation and improve preparative yields. The resulting benzo- and naphtho-fused BODIPYs display intense fluorescence in the red region, with emission maxima spanning 590-680 nm and fluorescence quantum yields ranging from 0.

Drug-induced hepatotoxicity (DIH), characterized by diverse phenotypes and complex mechanisms, remains a critical challenge in drug discovery. To systematically decode this diversity and complexity, we propose a multi-dimensional computational framework integrating molecular structure analysis with disease pathogenesis exploration, focusing on drug-induced intrahepatic cholestasis (DIIC) as a representative DIH subtype. First, a graph-based modularity maximization algorithm identified DIIC risk genes, forming a DIIC module and eight disease pathogenesis clusters.
