4-p-Tolyl-1,3,4,4a,5,6,7,8a-octahydro-2H-pyrano[2,3-d]pyrimidin-2-one

Abstract

The title compound, C14H18N2O2, which was obtained from an extended Biginelli reaction, contains a pyran ring with a chair conformation, a pyrimidine ring with a half-chair conformation and a benzene ring. The crystal structure is stabilized by an intermolecular hydrogen-bond network involving both NH groups and the carbonyl group.
