New isoxazolidinyl-based N-alkylethanolamines as new activators of human brain carbonic anhydrases

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2023
Carbonic anhydrases (CAs) are widespread metalloenzymes which catalyse the reversible hydration of carbon dioxide (CO2) to bicarbonate (HCO3−) and a proton, relevant in many physiological processes. In the last few years, the involvement of CA activation

Strategies for the Enantioselective Synthesis of 2-Isoxazolines and 2-Isoxazolin-5-ones Bearing Fully Substituted Stereocenters

open access: yes, 2022
Although there is an abundance of methods for the enantioselective synthesis of 2-isoxazolines and 2-isoxazolin-5-ones, relatively few of these approaches have been reported when these heterocycles bear fully substituted stereocenters. In this minireview,

Direct Nucleophilic Difluoromethylation of Aromatic Isoxazoles Activated by Electron-Withdrawing Groups Using (Difluoromethyl)trimethylsilane

open access: yesScienceOpen Research, 2014
The activation of aromatic diaryl isoxazoles with strong electron-withdrawing groups, such as the nitro, triflyl and the phenylsulfonyl groups, at the 4-position has enabled the first regio- and diastereoselective difluoromethylation at the 5-position of
