difference in distinguishing substrates of otherwise nearly identical chemical reactivities. A one‐pot cascadereaction involving nitromethane and two aliphatic aldehydes with similar reactivities has been developed (see scheme). The use of a biphasic reaction medium with two different organic catalysts results in the controlled incorporation of both aldehyde substrates into a single major cross‐product
