The choice of an appropriate electrophile is crucial in the design of targeted covalent inhibitors (TCIs). In this report, we systematically investigated the glutathione (GSH) reactivity of various haloacetamides and the aqueous stability of their thiol adducts. Our findings revealed that dihaloacetamides cover a broad range of GSH reactivity depending on the combination of the halogen atoms and the

A straightforward synthesis toward 2-fluorinated aziridines was developed via ring closure of β-fluorinated β-chloroamines, which were obtained via reduction of the corresponding α-fluorinated amides by borane. When 1-benzyl-2-fluoroaziridine was treated with methanol, reaction occurred at the 2-position, giving rise to N-benzyl-2,2-dimethoxyethylamine, while in the case of 1-benzyl-2,2-difluoroaziridine
