Csp3–H Bond Functionalization of α-Bromo Ketones for the Synthesis of α-Keto Thioamides Using Elemental Sulfur

An efficient metal- and additive-free synthesis of α-keto thioamides has been developed via sulfur oxidation of the C sp 3–H bond of α-bromo ketones with amines. This environmentally friendly strategy made it possible to synthesize a wide series of α-keto thioamides with broad functional group toler...

Zusammenfassung:An efficient metal- and additive-free synthesis of α-keto thioamides has been developed via sulfur oxidation of the C sp 3–H bond of α-bromo ketones with amines. This environmentally friendly strategy made it possible to synthesize a wide series of α-keto thioamides with broad functional group tolerance.
