Ethyl 5''-(2,6-dichlorophenyl)-1'-methyl-4-(1-naphthyl)-2,3''-dioxo-2,3,2'',3''-tetrahydro-1H-indole-3-spiro-2'-pyrrolidine-3'-spiro-2''-thiazolo[3'',2''-a]pyrimidine-6''-carboxylate ethyl acetate hemisolvate

Abstract: The asymmetric unit of the title compound, C₃₇H₃₀Cl₂N₄O₄S·0.5C₄H₈O₂, contains two crystallographically independent spiro molecules and an ethyl acetate solvent molecule. In both spiro molecules, the pyrrolidine ring adopts an envelope conformation. The thiazolidine and oxindole moieties are slightly distorted from planarity. The molecular structure is stabilized by C-HCl and C-HO interactions and the crystal structure is stabilized by N-HN and C-HO interactions.
