The regioselective palladiumcatalysed hydrostannylation of alkynes bearing a β-heteroatom affords mainly α-vinyltin(IV) compounds that are used as terminating species in palladiumcatalysed cyclisation–anion capture processes. The pharmacophore attached to the alkyne moiety permits the synthesis of sugars, nucleosides, purines, benzodiazepinones and β-lactams analogues in good yields.
chemotherapeutics that are structurally and mechanistically unique is needed due to the rapid rise of the cancer incidence across the globe. Here, we report the identification of irreversible, thiol-reactive diazepam derivatives as GPX4 modifiers and nanomolar inducers of ferroptosis in liver cancercells.
