In the title compound, C13H19NO3, the dioxane ring adopts a chair conformation. Its mean plane is inclined to the 4-methoxyphenyl ring by 70.34 (9)°. In the crystal, molecules are linked by pairs of C—HO hydrogen bonds, forming inversion dimers with an R22(16) ring motif. The dimers are linked via C—Hπ interactions, forming two-dimensional networks lying parallel to the ac plane.

In the title compound, C12H16FNO3, the dioxane ring adopts a chair conformation with the methyl groups and amine N atom in equatorial positions. The best plane through the dioxane ring makes a dihedral angle of 43.16 (8)° with the phenyl ring. In the crystal, pairs of C—HO hydrogen bonds link the molecules into centrosymmetric R22(8) dimers, which are linked into [100] chains by further C—HO hydrogen bonds. The N—H group does not participate in hydrogen bonding.
