Crystal structure of (1S,2R)-2-[(3R,4S)-3-methyl-4-phenyl-1,2,3,4-tetra­hydro­isoquinolin-2-yl]-1,2-di­phenyl­ethanol

The synthesis and crystal structure of the title compound, C(30)H(29)NO, are described. This compound is a member of the chiral di­hydro­iso­quinoline-derived family, used as building blocks for functional materials and as source of chirality in asymmetric synthesis, and was isolated as one of two diastereomeric β-amino alcohols, the title mol­ecule being found to be the (S,R) diastereoisomer. In the crystal, mol­ecules are packed in a herringbone manner parallel to (103) and (10[Image: see text]) via weak C—H⋯O and C—H⋯π(ring) inter­actions. Hirshfeld surface analysis showed that the surface contacts are predominantly H⋯H inter­actions (ca 75%). The crystal studied was refined as a two-component inversion twin.
