TL;DR: In this article, the preparation and regiospecific cerium(IV) sulfate oxidation of the substituted N-benzyl-β-aminoketones are described.
Abstract: Uber Darstellung und regiospezifische Cer(IV)sulfat-Oxidation substituierter N-Benzyl-β-aminoketone 3 wird berichtet. Die so erhaltenen 4-Benzoyl-1,2,3,4-tetrahydroisochinoline 4 werden mit Natriumborhydrid reduziert.
Oxidations with Cerium(IV) Sulfate: Intramolecular Cyclization of N-Benzyl-β-aminoketones Yielding 4-Benzoyl-1,2,3,4-tetrahydroisoquinolines
Preparation and regiospecific cerium(IV) sulfate oxidation of the substituted N-benzyl-β-aminoketones 3 are described. 4-Benzoyl-1,2,3,4-tetrahydroisoquinolines 4 so obtained are reduced by sodium borohydride.
