A NaCl-mediated electrochemical oxidation of amino acid carbamates (R = Boc, Cbz) afforded α-methoxylated α-amino acids. Subsequent acid-catalyzed elimination delivered valuable dehydroamino acid derivatives. The simplicity of our setup using graphite-electrodes was showcased, producing -Boc-ΔAla-OMe on a decagram scale.

Metal nanoclusters stabilized by N-heterocyclic carbene (NHC) ligands have attracted increasing interest for their special structures and diverse applications. However, developing synthetic strategies and extending the database of NHC-protected nanoclusters are still challenging tasks. In this work, a novel and rapid synthetic method is developed to prepare AuAg alloy nanocluster ligated by carbene based on the reactivity of nanoclusters.

The electrocatalytic reduction of nitrogenous waste offers a sustainable approach to producing nitrogen-containing chemicals. The selective synthesis of high-value hydroxylamine (NHOH) is challenging due to the instability of NHOH as an intermediate. Here, we present a rational electrocatalyst design strategy for promoting NHOH electrosynthesis by suppressing the competing pathways of further reduction.
