The reactivity of 2-vinylindoles with dimethyl acetylenedicarboxylate

Chemistry of 2-Vinylindoles: Synthesis and Applications

As a class of compounds, 2-vinylindoles have demonstrated a wide range of biological properties. Due to the general interest in these synthons, new divergent protocols of chemical synthesis have been...

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

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.

The title compound, C₂₃H₂₀N₂O₆S, crystallizes as a racemate in the space group P-1, with an overall L- or J-shape to each mol­ecule. Centrosymmetric pairs of mol­ecules are tandem hydrogen bonded between the hydro­per­oxy H atom and carbonyl O atom. A different centrosymmetric pairing has stacked S-tolyl rings, and a third pairing is L,J-inter­locked by the short leg. Except for stacked tolyl pairs, neighboring π-systems are much closer to orthogonal than coaxial. The title compound is the first example of a hydro­peroxide obtained from the autoxidation of a Diels–Alder adduct of a 2-vinyl­pyrrole.
