Conduramine B and a ‘condurithiol’, namely
(1S,2S,3R,6R)-6-aminocyclohex-4-ene-1,2,3-triol
and
(1R,2S,3R,6R)-6-sulfanylcyclohex-4-ene-1,2,3-triol,
have been prepared by the thermal rearrangement of an acetimidate and a
dithiocarbonate, respectively. Both the amine and the thiol are putative
inhibitors of β-xylosidases and, in order to mimic the natural substrate
more closely, an N- and an
S-pseudo-disaccharide have been prepared.
