All H atoms were placed in calculated positions and refined using a riding model. C-H distances: CH3, 0.98\%A; >CH2, 0.99\%A; =CH2, 0.95\%A;C-H, 1.00\%A. O-H distance: 0.84\%A. All carbon Uiso(H) values were constrained to be 1.2 times Ueq of the parent atom. The hydoxyl Uiso(H) value was constrained to be 1.5 times Ueq of the parent atom. In the absence of significant anomalous scattering effects, the absolute configuration could not be confirmed from the diffraction data; it was assumed from the known configuration of the starting material, and Friedel pairs were merged. Colin Kilner 14 March 2005 Refinement of F^2^ against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F^2^, conventional R-factors R are based on F, with F set to zero for negative F^2^. The threshold expression of F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F^2^ are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. ; _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w=1/[\s^2^(Fo^2^)+(0.0612P)^2^+0.1350P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _atom_sites_solution_hydrogens geom _refine_ls_hydrogen_treatment constr _refine_ls_extinction_method none _refine_ls_extinction_coef ? _refine_ls_number_reflns 2404 _refine_ls_number_parameters 260 _refine_ls_number_restraints 82 _refine_ls_R_factor_all 0.0715 _refine_ls_R_factor_gt 0.0430 _refine_ls_wR_factor_ref 0.1113 _refine_ls_wR_factor_gt 0.0980 _refine_ls_goodness_of_fit_ref 1.044 _refine_ls_restrained_S_all 1.034 _refine_ls_shift/su_max 0.001 _refine_ls_shift/su_mean 0.000 loop_ _atom_site_label _atom_site_type_symbol _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_occupancy _atom_site_symmetry_multiplicity _atom_site_calc_flag _atom_site_refinement_flags _atom_site_disorder_assembly _atom_site_disorder_group C1 C 0.2283(5) 0.6648(3) 0.59953(6) 0.0300(6) Uani 1 1 d . . .

C-H distances: CH3, 0.98\%A; >CH2, 0.99\%A; C-H, 1.00\%A. All carbon Uiso(H) values were constrained to be 1.2 times Ueq of the parent atom. In the absence of significant anomalous scattering effects, the absolute configuration could not be confirmed from the diffraction data; it was assumed from the known configuration of the starting material, and Friedel pairs were merged. Colin Kilner 14 March 2005 Refinement of F^2^ against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F^2^, conventional R-factors R are based on F, with F set to zero for negative F^2^. The threshold expression of F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F^2^ are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. ; _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w=1/[\s^2^(Fo^2^)+(0.0831P)^2^+0.0510P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _atom_sites_solution_hydrogens geom _refine_ls_hydrogen_treatment constr _refine_ls_extinction_method SHELXL _refine_ls_extinction_coef 0.076(18) _refine_ls_extinction_expression Fc^*^=kFc[1+0.001xFc^2^\l^3^/sin(2\q)]^-1/4^ _refine_ls_number_reflns 2039 _refine_ls_number_parameters 227 _refine_ls_number_restraints 1 _refine_ls_R_factor_all 0.0491 _refine_ls_R_factor_gt 0.0437 _refine_ls_wR_factor_ref 0.1169 _refine_ls_wR_factor_gt 0.1123 _refine_ls_goodness_of_fit_ref 1.032 _refine_ls_restrained_S_all 1.032 _refine_ls_shift/su_max 0.000 _refine_ls_shift/su_mean 0.000 loop_ _atom_site_label _atom_site_type_symbol _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_occupancy _atom_site_symmetry_multiplicity _atom_site_calc_flag _atom_site_refinement_flags _atom_site_disorder_assembly _atom_site_disorder_group C1 C 0.8323(3) 0.3092(3) 0.27455(18) 0.0348(5) Uani 1 1 d . . .

The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry.
