(8aRS)-8,8a-Dihydrofuro[3,2-f]indolizine-6,9(4H,7H)-dione

Abstract

The title compound, C10H9NO3, is a chiral molecule with one stereogenic carbon atom, but which crystallizes as a racemate in the centrosymmetric space group P21/n. The central six-membered ring of the indolizine moiety adopts a definite envelope conformation, while the conformation of the oxopyrrolidine ring is close to that of a flat-envelope with a maximum deviation of 0.352 (1) Å for the flap atom.
