Abstract:

The structures of 1, 4∶3, 6-dianhydro-β-D- fructofuranosyl 4-chloro-4-deoxy-α-D-galactopyranoside( 1),  1, 4∶3, 6-dianhydro-β-D-fructofuranosyl 3, 6-anhydro-4-chloro-4-deoxy-α-D-galactopyranoside (2) and 1, 6-dichloro-1, 6-dideoxy-β-D-fructofuranosyl 3, 6-anhydro-4-chloro-4-deoxy-α-D-galactopyranoside (3) were elucidated using 1D and 2D NMR spectroscopy (1H NMR,  13C NMR,  DEPT-135,  1H-1H COSY,  HSQC,  HMBC) and HRMS spectra. 1H and 13C chemical shifts of these compounds were assigned.

Key words: NMR,  assignments, anhydrosucrose, sucralose, 4, 6, 1′, 6′-tetrachloro- 4, 6, 1′, 6′-tetradeoxy-galactosucrose
