Synthesis of functionalized carbamates and quinones via sequential oxidation of salicylaldehydes using TBHP as the oxidant

[Display omitted] A sequential oxidative approach was designed to functionalize salicylaldehyde derivatives and provide corresponding bi-functional amide-carbamate and amide-quinone units. A combination of metal/metal free conditions and TBHP as the external oxidant provided the products in moderate...

Zusammenfassung:[Display omitted] A sequential oxidative approach was designed to functionalize salicylaldehyde derivatives and provide corresponding bi-functional amide-carbamate and amide-quinone units. A combination of metal/metal free conditions and TBHP as the external oxidant provided the products in moderate to excellent yields (49–91%).
