Crystal structure of (±)-(3aR,5R,8bR)-5-hydroperoxy-2-phenyl-6-tosyl-4,5,6,8b-tetrahydropyrrolo[3,4-e]indole-1,3(2H,3aH)-dione

Abstract

The title compound crystallized as racemic tandem OO—H⋯O=C hydrogen-bonded dimers stacked along [100] in the space group P . This is the first crystallographically characterized example of a hydro­peroxide obtained from the autoxidation of a Diels–Alder adduct of a 2-vinyl five-membered heterocycle.
