5′-Amino-1,3-dioxo-2′,3′-dihydro-7′H-spiro[indane-2,7′-thieno[3,2-b]pyran]-6′-carbonitrile 1′,1′-dioxide
The title compound, C(16)H(10)N(2)O(5)S, was synthesized via the condesation of dihydrothiophen-3(2H)-one 1,1-dioxide, 1H-indene-1,2,3-trione and malononitrile in ethanol. The 2,3-dihydrothiophene 1,1-dioxide and pyran rings adopt envelope conformations. The mean planes through the planar part o...

| description | The title compound, C(16)H(10)N(2)O(5)S, was synthesized via the condesation of dihydrothiophen-3(2H)-one 1,1-dioxide, 1H-indene-1,2,3-trione and malononitrile in ethanol. The 2,3-dihydrothiophene 1,1-dioxide and pyran rings adopt envelope conformations. The mean planes through the planar part of the pyran ring and the benzene ring are nearly perpendicular, forming a dihedral angle of 88.40 (7)°. The crystal packing is stabilized by intermolecular N—H⋯O and N—H⋯N hydrogen bonds with the sulfone O atom and the cyano N atom acting as acceptors. |
