✦ Synopsis

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 coupling pattern('doublet' vs. 'multiplet').
