Diastereoselective Synthesis and Biological Evaluation of Spiro[chromane-2,4′-pyrimidin]-2′(3′H)-ones as Novel Antimicrobial and Antioxidant Agents

Molecules
This study reports an improved diastereoselective synthesis of substituted spiro[chromane-2,4′-pyrimidin]-2′(3′H)-ones via the acid-catalyzed condensation of 6-styryl-4-aryldihydropyrimidin-2-ones with resorcinol, 2-methylresorcinol, and pyrogallol.

Redox‐Mediated Amination of Pyrogallol‐Based Polyphenols

Chemistry – A European Journal
AbstractFlavonoids are known to covalently modify amyloidogenic peptides by amination reactions. The underlying coupling process between polyphenols and N‐nucleophiles is assessed by several in vitro and in silico approaches. The coupling reaction involves a sequence of oxidative dearomatization, amination, and reductive amination (ODARA) reaction ...

Obtention of a Sensitive Acylated Pyrogallol[4]arene-Based Sensor for the Detection of Carnitine: A Spectroscopic and DRX Study

Analytica
Complexation between carnitine and acetylated or benzylated pyrogallol[4]arenes was studied in DMSO via dynamic NMR, UV-vis spectroscopy, and in the gas phase via electrospray ionization-mass spectrometry (ESI-MS).
