Abstract

AbstractA convergent paired electrolysis method for the synthesis of 1‐pyrazolyl‐substituted tetrahydroisoquinolines has been developed. The reaction proceeded without any transition metal catalyst and chemical oxidant. The desired products could be isolated in high yields (80–99%) in 60–80 minutes. The Faradaic efficiency was 108% and gram‐scale synthesis (84%) could be carried out. Mechanistic studies revealed that the C−N bond formation process might mainly involve a nucleophilic addition reaction.
