The Persistence of Hydrogen Bonds in Pyrimidinones: From Solution to Crystal [PDF]

ACS Organic & Inorganic Au
Pyrimidinone scaffolds are present in a wide array of molecules with synthetic and pharmacological utility. The inherent properties of these compounds may be attributed to intermolecular interactions analogous to the interactions that molecules tend to establish with active sites.

Crystal structures of (E)-2-amino-4-methylsulfanyl-6-oxo-1-(1-phenylethylideneamino)-1,6-dihydropyrimidine-5-carbonitrile and (E)-2-amino-4-methylsulfanyl-6-oxo-1-[1-(pyridin-2-yl)ethylideneamino]-1,6-dihydropyrimidine-5-carbonitrile

Acta Crystallographica Section E: Crystallographic Communications, 2021
The title compounds 3a, C14H13N5OS, and 3b, C13H12N6OS, both show an E configuration about the N=C bond and a planar NH2 group. The molecules, which only differ in the presence of a phenyl (in 3a) or pyridyl (in 3b) substituent, are closely similar ...
