(6 S ,7 S ,8 S ,8a S )-6-Ethyl-3-oxo-1,2,3,5,6,7,8,8a-octahydroindolizine-7,8-diyl diacetate

In the molecular structure of the title compound, C14H21NO5, the six-membered ring of the indolizine moiety adopts a chair conformation. There are two independent molecules in the asymmetric unit. The oxopyrrolidine ring attached to the indolizine ring system is nearly planar, with mean deviations of 0.018 (3) and 0.010 (3) Å for the two molecules. The absolute configuration of the title compound was assigned from the synthesis.
