Abstract
The potential porphyrin precursor ethyl 5-p-tolylsulfonyl-2,4,5,6-tetrahydropyrrolo[3,4-c]pyrrole-1- carboxylate has been synthesized and its crystal structure determined by X-ray methods, giving a refinement residual R 0·038 for 5130 observed reflections. Crystals are triclinic, space group P 1, with Z = 4 in a cell of dimensions a 10·5030(6), b 11·2843(8), c 15·236(1) Å, α 109·419(6), β 97 · 697(6), γ 95 · 651(6)°. The two molecules in the crystallographic repeating unit are pseudo-mirror-related, and the heterocyclic system is almost planar in both molecules.https://doi.org/10.1071/CH99023
