Zusammenfassung:
Impressive tolerance is displayed in the efficient and chemoselective organocatalytic transfer hydrogenation of α,β‐unsaturated aldehydes in the presence of a Hantzsch dihydropyridine and a catalytic amount of dibenzylammonium trifluoroacetate (see scheme). Various sensitive functional groups such as the nitro, cyano, alkenyl, and benzyloxy groups survive these reaction conditions.
