N,N'-Methylenebis[(S)-5-phenyloxazolidine]

The 2:3 condensation product, C₁₉H₂₂N₂O₂, formed by reaction of (S)-(+)-2-amino-1-phenylethanol with formaldehyde has an N,N'-methylenebis(oxazolidine) heterocyclic skeleton. The two oxazolidine rings have envelope-type conformations, with their N atoms displaced by 0.604 (5) and 0.537 (6) Å from the mean planes formed by the remaining four atoms of each ring. The dihedral angle between the two planes is 110.2 (2)°.
