Various steps involved in the preparation of partially methylated alditol acetates (PMAAs) from glycoprotein-derived carbohydrates were improved to obtain the derivatives in a rapid manner with excellent yields. Carbohydrates were permethylated in dimethyl sulfoxide (DMSO), using a fine suspension o

A method is described for the analysis of positions of substitution of O-methyl and O-ethyl groups in commercial samples of O-methylcellulose and O-ethylcellulose, respectively. The method requires perethylation of O-methyl-cellulose and permethylation of O-ethylcellulose. Subsequent reductive cleav

Methylation analysis is still one of the most important methods for the structure analysis of oligosac~harides I. Gas chromatography-mass spe~tromet~, as well as 13C-and 'H-n.m.r. spectroscopy, is commonly used for identification of partially methylated monosaccharides. This requires numerous standa
