usually proposed. Here we present a full account dealing with the enantioselective phase‐transfer‐catalyzedintramolecular aza‐Michael reaction (IMAMR) of indolyl esters, as a valuable synthetic tool to obtain added‐value compounds, such as dihydro‐pyrazinoindolinones. A combined computational and experimentalinvestigation has been carried out to elucidate the key mechanistic aspects of this process.
