Due to the enermous roles of cyclodextrin combining with small organic molecules,
more recent interests study about the manipulation of cyclodextrin structure giving better
performance for any kinds of field but they presented long synthetis steps as producing the
precursors. This study points out the synthesis of precursor of ?-cyclodextrin analouges with
maltotriose as raw materials giving the short synthesis steps. The product structures were
analysed by Fourier Transform Infrared (FTIR) Specstroscopy,and characterised by 1H-,
13CNMR, COSY NMR, and ESI Mass Spectroscopy. The result showed that O-acetylation
reaction produced maltotriose derivative 1 (95%), thioglycosidation reaction produced
maltotriose derivative 2 (54%), de-acetylation reaction produced maltotriose derivative 3
(97%), O-benzylidation reaction produced a mixture of maltotriose derivatives 4, Omethylation reaction produced maltotriose derivative 5 (46%) and de-benzylidation reaction
produced maltotriose derivative 6 (85%) |
