Synthesis and crystal structure of 3-Ethyl-2-(ethylthio)-5-(4-oxo-4H-chromen-3-yl methylene)imidazolidine-4-one
Özet
The structure of the title compound, C17H16N2O3S, was prepared by the reaction of chromone-3-carboxaldehyde with 2-thioxo-imidazolidine-4-one and ethyl iodide. The five-membered imidazolidine ring is in a planar conformation with a maximum deviation of 0.013(1)Å, and making a dihedral angle of 5.36(5)° with the benzopyran ring system. The crystal structure is stabilized by intra and intermolecular hydrogen-bond interactions. 2007 © The Japan Society for Analytical Chemistry.
