Two substituted 2-pyrrolin-5-ones: chains built from a single N-HO hydrogen bond

Z.-F. Zhang, J.-G. Wang, S.-Q. Wang and G.-R. Qu

Abstract: In each of methyl 2-methyl-5-oxo-2-pyrroline-3-carboxylate, C₇H₉NO₃, and 3-acetyl-2-methyl-2-pyrrolin-5-one, C₇H₉NO₂, the pyrrolinone ring is planar. In each structure, molecules are linked into simple chains by way of a single N-HO hydrogen bond.

Formula: C₇H₉NO₃ and C₇H₉NO₂
