An organocatalytic oxidative synthesis of N-protected tetrahydroisoquinolines is described by C-H functionalization via intermediate peroxides. The peroxides were synthesized from tert-butylhydroperoxide under metal-free thermal conditions and were converted into the final products by Bronsted acid catalyzed substitution. The nucleophile scope was investigated in detail and proved to be broad; N-deprotection of the coupling products could also be achieved. An organocatalytic oxidative synthesis of N-protected tetrahydroisoquinolines was achieved by C-H functionalization via Intermediate PeroxideS (CHIPS). The peroxides were synthesized under metal-free thermal conditions and were converted into the final products by reaction with a variety of nucleophiles by using Bronsted acid catalysis. Copyright
