Cross dehydrogenative coupling of <i>N</i>-aryltetrahydroisoquinolines (sp³ C–H) with indoles (sp² C–H) using a heterogeneous mesoporous manganese oxide catalyst

Abstract

We disclose a novel, heterogeneous catalytic approach for selective coupling of C1 of <italic>N</italic>-aryltetrahydroisoquinolines with C3 of indoles in the presence of mesoporous manganese oxides.
