Investigation of three stilbene derivatives by x-ray crystallography and NMR spectroscopy

Journal article, 1998

Crystal structure determinations demonstrate unambiguously the steric assignments of (Z)-2-hydroxy-3,3',4'-trimethoxystilbene (C17H18O4), (E)-2-hydroxy-3,3',4'-trimethoxystilbene (C17H18O4) and (E)-2-acetoxy-3,3',4'-trimethoxystilbene (C19H20O5) C-13 NMR data and UV data for the compounds are also reported. The steric assignments of structurally related compounds described in the literature are discussed on the basis of the crystallographic and spectral results.
