Synthesis of six inositol stereoisomers was successfully carried out via conduritol intermediates prepared from myo-inositol. Dihydroxylation and epoxidation followed by ring opening of the conduritol B, C and F derivatives gave epi-, allo-, muco-, neo-, DL-chiro- and scyllo-inositol. The cis-inositol derivative, which may not be prepared by this approach, was synthesized in 5 steps via 2-O-benzoyl-myo-inositol

The influence of protectinggroups on the reactivity of glycosyl acceptors has been investigated through a series of competitive glycosylation experiments using differently substituted C2 symmetric D-chiro-inositol derivatives. It has been shown that, for a given glycosyl donor, the protective group pattern effectively modulates the reactivity of these derivatives in the glycosylation reaction.
D-Glucurono-6,3-lactone was converted to optically active and partially protected inositols. The synthetic strategy involves an efficient conversion of the D-gluco configuration to the L-ido configuration and reductive cyclization of dials to cyclitols.
Compounds having a mimetic or antagonistic property of an inositol phosphoglycan, and the uses of these compounds are disclosed, together with the use, e.g. to treat a condition ameliorated by administration of an IPG second messenger or an IPG antagonist thereof. In particular, the compounds are based on the 1,6 linkage of a sugar residue and a cyclitol.
