Abstract: Trifluoroacetyl derivatives of all theoretically possible isomers of O-acetyl-l,6-anhydro-β -D-glucopyranoses have been prepared and studied by
electron-impact mass spectrometry as well as by combination with gas
chromatography. On the basis of the knowledge obtained on fragmentation,
from the intensities of three characteristic fragments, namely m/z = 81,131,
and 194, a procedure for simple identification of the compounds of this type
has been elaborated.
The method is suitable for following hydrolyses of acetates of 1,6-anhydrohexopyranoses by means of gas chromatography and mass spectrometry.
