(–)-1-Benzyl-4-[1(S)-phenyl­ethyl­amino]-5,6-dihydro­pyridin-2(1H)-one

In the title mol­ecule, C₂₀H₂₂N₂O, the pyridine heterocycle has an envelope conformation. The crystal packing is stabilized by inter­molecular N—H...O hydrogen bonds, which link the mol­ecules into chains along the [10] direction.

(–)-1-Benzyl-4-[(1R)-2-hydr­oxy-1-phenyl­ethyl­amino]-5,6-dihydro­pyridin-2(1H)-one

In the title mol­ecule, C₂₀H₂₂N₂O₂, the pyridine heterocycle has an envelope conformation and is stabilized as an enamine tautomer. The crystal packing is stabilized by strong inter­molecular O—H...O hydrogen bonds, which link the mol­ecules into chains along the b axis.
