Molecules of two related 1,2-amino alcohols are linked via N—H⋯O=S hydrogen bonds, forming chains along [100] for the first compound and along [010] for the second compound., The title compounds, C22H31NO2S, (1), and C23H33NO2S, (2), are related protected 1,2-amino alcohols. They differ in the substituents on the benzene ring, viz. 2,6-dimethylphenyl in (1) and 2,4,6-trimethylphenyl in (2). The plane of the phenyl ring is inclined to that of the benzene ring by 28.52 (7)° in (1) and by 44.65 (19)° in (2). In the crystal of (1), N—H⋯O=S and C—H⋯O=S hydrogen bonds link molecules, forming chains along [100], while in (2), similar hydrogen bonds link molecules into chains along [010]. The absolute structures of both compounds were determined by resonance scattering.
