Studies on quinoline and isoquinoline derivatives. VIII. Hydration and hydrogenation of ethynyl substituents attached to the pyridine moiety of quinoline and isoquinoline rings.
Catalyst-free, direct electrooxidative phenol derivatives C(sp3)–H mono- and di-alkylation reaction have been developed. In contrast to previous typical oxidative and electrochemical coupling, this electrosynthetic approach enables selective mono- and di-alkylations through metal- and external oxidant-free mild conditions via easily available electrodes. Advances of this strategy were proven by an
