Abstract
The structure of the title compound, C12H16O3, was determined by X-rays.M r =208.26, triclinic, space groupP¯1,a=7.802(2),b=8.449(2),c=9.069(1) Å,α=90.79(1)°,β=105.57(1)°, γ=106.07(1)°,Z=2,D x =1.26 Mg m−3; MoKα radiation (graphite crystal monochromator, λ=0.71069 Å),μ(MoKα)=0.96 cm−1,T=290 K. Final conventionalR-factor=0.046,R w =0.067 for 3009 “observed” reflections and 184 variables. The structure was solved using Patterson methods andDirdif, and the resulting all cis-endo configuration of the alcohol group on C(3) and the ethoxy group on C(5) shows that the stereochemistry of the metal-mediated addition reaction involved is solely determined by steric factors.
