The total synthesis of (+)-hapalindole Q has been achieved. The key step is a Diels-Alder reaction mediated by MacMillan's organocatalyst to provide the critical intermediate with high enantiose-lectivity (93% ee). This step establishes the proper arrangement of the required four contiguous stereocenters, including the quaternary center, and represents the first successful application of an enantioselective organomediated Diels-Alder reaction in total synthesis.
