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.
