Abstract

The title compound crystallizes in the monoclinic space group P21/n, witha=9.590(6),b=11.574(2),c=9.609(2) Å, β=105.72(3)o andZ=4. The structure was solved by direct methods and refined by full matrix least squares methods toR=0.039 for 1899 observed reflections. The stereochemistry of this 6/5 ring system is found to becis-fused with C(3)−C(4) bond in the axial and N(9)−O(1) bond in equatorial disposition. The six-membered ring in the molecule is in the chair and the five-membered isoxazolidine ring adopts an envelope conformation.
