Crystal structures of ethyl (2S*,2′R*)-1′-methyl-2′′,3-dioxo-2,3-di­hydro­dispiro­[1-benzo­thio­phene-2,3′-pyrrolidine-2′,3′′-indoline]-4′-carboxyl­ate and ethyl (2S*,2′R*)-5′′-chloro-1′-methyl-2′′,3-dioxo-2,3-di­hydro­dispiro­[1-benzo­thio­phene-2,3′-pyrrolidine-2′,3′′-indoline]-4′-carboxyl­ate

In the title compounds, C(22)H(20)N(2)O(4)S, (I), and C(22)H(19)ClN(2)O(4)S, (II), the pyrrolidine rings have twist conformations on the spiro–spiro C—C bonds. In (I), the five-membered ring of the oxindole moiety has an envelope conformation with the spiro C atom as the flap, while in (II) this rin...
