Gas liquid chromatography and mass spectrometry of methyl ethers of methyl n acetyl n methyl beta d neuraminate methyl glycoside



Gas liquid chromatography and mass spectrometry of methyl ethers of methyl n acetyl n methyl beta d neuraminate methyl glycoside



Journal of Chromatography 210(3): 487-504



Partial methylation of methyl N-acetyl-.beta.-D-neuraminate methyl glycoside using methyl iodide and silver oxide gives a mixture of methyl ethers of methyl N-acetyl-N-methyl-.beta.-D-neuraminate methyl glycoside, which was fractionated by chloroform-water partition followed by preparative column chromatography on silica gel. After trimethylsilylation of the fractions, GLC on OV-101 and mass spectrometry facilitated the identification of 13 methyl ethers.
