要旨:
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 Brønsted 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.
