Abstract
AbstractA new quinoxaline 1,4‐dioxide benzylsulfanyl derivative was tested under mild conditions in copper‐mediated Liebeskind–Srogl (LS) cross‐coupling reactions with arene boronic acids. These first organometallic cross‐coupling reactions performed on a quinoxaline 1,4‐dioxide derivative open new perspectives in medicinal chemistry. They represent also the first LS cross‐couplings run with an electrophile equipped with an aryl N‐oxide moiety.
