Abstract

Selective cross-dehydrogenative coupling of N-phenyltetrahydroisoquinoline with carbon nucleophiles such as dimethyl malonate, ethyl acetoacetate, and nitromethane was demonstrated in complete aqueous media using poly(2-methoxyaniline-5-sulfonic acid)/gold nanoparticles under molecular oxygen.
