Source of materials
The title compound was prepared from L-phenylalanine by diazotization, esterification, condensation, hydrolyzation and decarboxylation. It was recrystallized from water to give colorless crystals for single-crystal X-ray diffraction.
Experimental details
All H atoms were positioned geometrically and treated as riding, with C—H bond lengths constrained to 0.93 Å for phenyl hydrogen atoms, 0.97 Å for methylene H atoms and 0.97 Å for methyne H atoms with Uiso(H) = 1.2Ueq(C). The O—H bond length was constrained to 0.82 Å and the Uiso(H) was set to 1.5Ueq(O). The presence of the S enantiomer was concluded from the synthesis.
Comment
(S)-2-benzylsuccinic acid is a valuable compound, which was employed as a key intermediate for hypoglycemic KAD-1229 by means of asymmetric alkylation of N-acylsultam [3, 4] . (S)-2-benzylsuccinic acid can be synthesized by various procedures. The preparation of (S)-2-benzylsuccinic acid from L-phenylalanine is considered to be one of the most clean, efficient and convenient processes [5, 6] .
The asymmetric unit of the title structure contains one independent molecule. All bond lengths and angles of this molecule are in the expected ranges. The molecules are packed in the crystal structure via two intermolecular strong classical hydrogen bonds, O4–H4A⋅⋅⋅O2i and O1–H1A⋅⋅⋅O2ii. The H⋅⋅⋅A distances are 1.80 and 1.87 Å, respectively and the angles are 172 and 174°, respectively. Symmetry codes: (i) x + 1/2, − y + 1/2, − z + 1; (ii) x−1/2, − y + 1/2, − z + 1.
