X-ray Structures of Cis and Trans-diisomers of 1,2-dimethyl-3-ethyl 2,3-dihydropyrrolo[1,2-f]phenanthridine-1,2,3-tricarboxylate

Primary tabs

Tinant, Bernard [UCL] Declercq, Jean-Paul [UCL] Dostal, J. Potacek, M.

The two title isomers were obtained in 1,3-dipolar cycloaddition of the same ylide 2, with dimethyl fumarate and dimethyl maleate, respectively. Their stereochemistry was established by X-ray diffraction analysis. The molecular geometries of the two isomers are compared.
