ADVANCES IN CARBOHYDRATE CHEMISTRY
The (—) enantiomorph was similarly prepared from (—)-quebrachitol (93, Z—
methyl ether). Direct hydroxylation of 1,3-cyclohexadiene with permanganate
unexpectedly gave the DL(123/4) tetrol ( 55), presumably because initial trans1 ...

Chemistry of The Carbohydrates
Hydriodic acid at the boiling point (127°) demethylates the compound to d-
inositol. l-Inositol, the optical enantiomorph of d-inositol, likewise occurs as a
monomethyl ether, quebrachitol, which is not the enantiomorph of pinitol. It is
obtained by ...
