C5 and C7 intramolecular hydrogen bonds stabilize the structure of N-pyrazinoyl-gabapentin (Pyr-Gpn-OH)

N. A. Wani, V. K. Gupta, R. Kant, S. Aravinda and R. Rai

Synopsis: In the title N-protected derivative of gabapentin (Gpn), the molecular conformation is stabilized by intramolecular five- (C5) and seven-membered (C7) hydrogen-bonded rings. The packing of the molecules reveals O-H...O and C-H...N intermolecular hydrogen bonds, together with [pi]-[pi] interactions.

Formula: C14H19N3O3
