VI 18 Page 1629 Boger Supplemental Page 15 Experimental A colorless, plate like crystal (0.04x0.13x0.26 mm) was mounted alongwith the largest dimension and data were collected with a Rigaku AFC6R diffractometer equipped with a copper rotating anode and a highly oriented graphite monochromator. A constant scan speed of 4o/min in w was used and the weak reflections [I<5o(I)] were rescanned to a maximum of 4 times and the counts accumulated to assure good counting statistics. The intensities of three monitor reflections measured after during 51 hrs of X-ray exposure. Unit cell every 200 reflections did not change significantly dimensions and standard deviations were obtained by least squares fit to 25 reflections (50<20< ). The data were corrected for Lorentz and polarization effects and an absorption correction based on psi scan was applied. See Table 1 for cell parameters and other relevant data. The systematic absences (hkl, h+k=2n+l) indicated a choice among the space groups C2, Cm and C2/m. Since the compound is chiral and can only have a two fold site symmetry, C2 was chosen and later confirmed correct because of successful refinement of the structure. Z=2 in this space group suggests that the molecule has a two fold site symmetry. The structure was solved by directi methods using SHELXS86. Nitrogen and and oxygen atoms were refined anisotropically and carbon atoms isotropically by the full matrix least-squares method. The function minimized was Ew(IFI-11Fc ) 2. Hydrogen atoms were refined the wih dea afixe postios oc*2 in the ideal positions with a fixed isotropic U values of 0.08A. A weighting scheme of the form w=1/[a 2(F)+gF 2] with g=0.001 was used. There was no evidence of secondary extinction; therefore it was not applied. The refinement converged to the R indices given in the Table 1 which also includes the A/a and Ap in max the last cycles of refinement. The final difference map was devoid of significant features. All calculations were done on a Silicon graphics Personal Iris 4D/35 and an IBM compatible PC using programs TEXSAN (data reductiong), SHELXS86(structure solution) and SHELXTL (refinement and plotting). Final atomic coordinates are listed in Table 2 and selected bond lengths and bond angles in Table 3. References TEXSAN structure Analysis Package. Molecular Structure Corporation.
