In the course of continuing studies of sesquiterpene oligosaccharides, Mukuroziosides, we have found that 'H NMR signal of C,\* -methylene proton for the diastereomeric pairs of @)and (S)-MTPA[a-methoxy-a-trifluoromethylphenyl acetic acid] 1) esters of Mukurozidiol(L) appears as distinctly different
An assignment of relative configurations has been achieved for the diastereomeric racernates(lR2R,lS2S) and (1R2S, 1S2R) of 3,3-dimethyl-l,2-diphenylbuta~-l-ol through the comparative analysis of the respective chemical shifts induced by Eu(fod), in the 'H and '"C NMR spectra, and the corresponding
