The title compound, C 9 H 12 N 2 O 3 , was synthesized by the reaction in ethanol of ethane-1,2-diamine and 3-[bis(methylthio)methylene]-6-methyl-3,4,5,6-tetrahydro-2H-pyran-2,4dione. Two intramolecular N-HÁ Á ÁO hydrogen bonds induce a high degree of planarity.
In the title molecule, C 31 H 28 N 2 O 2 , the piperidinone ring adopts the usual twist-boat conformation. The aryl rings at positions 2 and 3 are axial and those at positions 5 and 6 are equatorial. In the crystal structure, there are no hydrogen bonds nor are there any significant Á Á Á stacking i
