SYNTHESIS OF CYCLIC NIGEROSYLNIGEROSE (CNN) BIS-IMIDAZOLIUM SALTS

摘要

Cyclic nigerosyl-(1 -> 6)-nigerose (CNN) monotosylate 1 and CNN ditosylate 2 were prepared and characterized by MALDI-TOF mass and NMR Spectroscopies. CNN bis-imidazolium salts 3 were also obtained by nucleophilic displacement reaction of 2 with imidazoles.
