A novel synthesis of didehydroamino acid (DDAA) esters 4 is described, starting from aldimines 1. The mechanism for this reaction involves the cycloaddition of an azomethine ylide 2 to an imine 1, followed by the base-catalysed ring-opening of the imidazolidine intermediate 6. This method has also been extended to the synthesis of DDAA esters 4h-j catalysed by an imine 1a.
