Syn- and anticlinal isomers of 2a'-acetoxy-1,7'-diacetyl-7',7a'-dihydro-2-oxospiro[1H-indole-3(2H),2'(2a'H)-oxeto[3,2-b]indole]

Abstract: In the syn- and anticlinal isomers of the title compound, C₂₂H₁₈N₂O₆, the indole moiety is not completely planar, with the pyrrolidine ring being distorted very slightly towards a conformation intermediate between half-chair and envelope. The molecular and packing structures in the crystals of these isomers are stabilized by C-HO interactions.

Formula: Two isomers of C₂₂H₁₈N₂O₆
