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, C16H10N2O5S, 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...
