The invention relates to a process for the preparation of an α-amino carbonyl compound by reacting an imine starting material with a suitable electrophile in the presence of a base. This process has the advantage that the imine starting materials can be prepared from glyoxylic acid esters or glyoxylic acid ester derivatives and α-hydrogen containing primary amines, which are usually cheap and readily available. These imine starting materials can usually be prepared with a high yield and/or almost without the formation of any side products.
