3-Ethyl-4-hydroxy-8-methoxyquinolin-2(1H)-one
In the title compound, C(12)H(13)NO(3), the quinoline ring system is approximately planar with a maximum deviation from the least-squares plane of 0.058 (2) Å. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into chains running along the b-axis direction. The chains also feature π-π inter-actions between pyridine and benzene rings of inversion-related mol-ecules [centroid-cen...

Mol-ecules of the title spiro-[4.5]decane derivative, C(17)H(30)N(2)O(3)S, are linked by paired O-H⋯N hydrogen bonds into centrosymmetric R(2) (2)(16) dimers and these dimers are linked into a three-dimensional framework structure by C-H⋯O interactions.
متن کاملAntioxidant Activity of 3-[N-(Acylhydrazono)ethyl]-4-hydroxy-coumarins.
A series of 3-acylhydrazono-4-hydroxycoumarins were synthesized via condensation of 3-acetyl-4-hydroxycoumarin with appropriate hydrazides. The structures of the newly-synthesized compounds were characterized by spectral and elememental analysis or HRMS measurements. Their antioxidant properties were evaluated by using scavenging effects on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical as well a...
