[4-(4-Meth­oxy­phen­yl)-1-methyl-3-nitro­pyrrolidin-3-yl]methanol

In the title compound, C₁₃H₁₈N₂O₄, the dihedral angle between the benzene and pyrrolidine (all atoms) rings is 70.6 (1)°. The pyrrolidine ring adopts a half-chair conformation. In the crystal, mol­ecules form chains along the c-axis direction linked by O—H...N hydrogen bonds, which are then connected by C—H...O inter­actions, forming a sheet parallel to the bc plane.

2-Chloro-1-(3,3-dimethyl-2,6-di­phenyl­piperidin-1-yl)ethanone

In the title compound, C₂₁H₂₄ClNO, the piperidine ring adopts a chair conformation. The two phenyl rings are inclined to one another by 20.7 (1)°, and are inclined to the mean plane of the four planar atoms of the piperidine ring by 87.64 (10) and 70.8 (1)°. The mol­ecular structure features short intra­molecular C—H...Cl and C—H...O contacts. In the crystal, there are no significant inter­molecular inter­actions present.
