A general, straightforward, and practical access to multi‐substituted chiral quinoxalin‐2‐ones has been achieved based on the copper(I) chloride‐dimethylethylenediamine (DMEDA) catalyst system. With the use of 1 mol% copper(I) chloride, structurally diverse quinoxalin‐2‐ones were generated with high optical purity from readily available starting materials, 2‐haloanilines and α‐amino acids, in a one‐pot manner.
