Separation of Racemic and Meso-1,2-Bis(2-[(2-Bromo-4,5-Dimethoxyphenyl)Hydroxymethyl]-4,5-Dimethoxybenzyl]-4,5-Dimethoxybenzenes by Host-Guest Inclusion
Diastereoisomers of title compounds were separated by inclusion of solvent and their stereostructures were determined by H-1-NMR measurement using a chiral shift reagent, Eu(tfc)(3).
