The first memory‐of‐chirality reaction in flash chemistry is reported: it allows the enantioselective synthesis of quaternary α‐amino acid derivatives with reaction residence times of less than three minutes. This proof of concept shows that larger product quantities can be synthesized in short reaction times.
A new methodology for the asymmetric synthesis of quaternary alpha-substituted amino acids using memory of chirality has been developed. The strategy utilizes the dynamic axial chirality of tertiary aromatic amides to memorize the initial chirality of an alpha-amino acid during an enolization step. Starting from five different l-amino acids, the corresponding oxazolidin-5-ones containing a tertiary
