title: (6S,7S,8S,8aS)-6-Ethyl-3-oxo-1,2,3,5,6,7,8,8a-octa-hydro-indolizine-7,8-diyl diacetate.
abstract: In the mol-ecular structure of the title compound, C(14)H(21)NO(5), the six-membered ring of the indolizine moiety adopts a chair conformation. There are two independent mol-ecules 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 mol-ecules. The absolute configuration of the title compound was assigned from the synthesis.
