We describe the enantioselective oxidative cross‐coupling of secondary amines with ketones by combining the non‐natural catalytic activity of lipase with electrosynthesis. Various 2,2‐disubstituted 3‐carbonyl indoles with a stereogenic quaternary carbon center were synthesized from 2‐substituted indoles in yields up to 78 % with good enantio‐ and diastereoselectivities (up to 96 : 4 e.r. and >20...

Rechargeable aqueous proton batteries are promising competitors for the next generation of energy storage systems with the fast diffusion kinetics and wide availability of protons. However, poor cycling stability is a big challenge for proton batteries due to the attachment of water molecules to the electrode surface in acid electrolytes. Here, a hydrogen‐bond disrupting electrolyte strategy to boost...
