Crystal structure and Hirshfeld surface analysis of 4,5-dibromo-6-methyl-2-phenyl-2,3,3a,4,5,6,7,7a-octahydro-3a,6-epoxy-1H-isoindol-1-one

In the title compound, C15H15Br2NO2, two bridged tetrahydrofuran rings adopt envelope conformations with the O atom as the flap. The pyrrolidine ring also adopts an envelope conformation with the spiro C atom as the flap. In the crystal, the molecules are linked into dimers by pairs of C - H⋯O hydrogen bonds, thus generating R22(18) rings. The crystal packing is dominated by H⋯H, Br⋯H, H⋯π and Br⋯π interactions. One of the Br atoms is disordered over two sites with occupation ratio of 0.833 (8):0.167 (8). © 2021.
