ligand-free, transition metal-free direct C–H functionalization
of quinones with diaryliodonium salts has been
developed for the first time. The transformation was promoted only
through the use of a base and gave aryl quinone derivatives in moderate
to good yields. This methodology provided an effective and easy way
to synthesize β-secretase
inhibitors. The radical trapping experiments showed that this progress
was the radical mechanism.
