Relative reactivity of hydroxyl groups in inositol derivatives: role of metal ion chelation
Devaraj, Subramanian,Jagdhane, Rajendra C.,Shashidhar, Mysore S.
experimental part, p. 1159 - 1166 (2009/10/04)
O-Alkylation of myo-inositol derivatives containing more than one hydroxyl group via their alkali metal alkoxides (sodium or lithium) preferentially occurs at a hydroxyl group having a vicinal cis-oxygen atom. In general the observed selectivity is relatively higher for lithium alkoxides than for the corresponding sodium alkoxide. The observed regioselectivity is also dependent on other factors such as the solvent and reaction temperature. A perusal of the results presented in this article as well as those available in the literature suggests that chelation of metal ions by inositol derivatives plays a significant role in the observed regioselectivity. Steric factors associated with the axial or equatorial disposition of the reacting hydroxyl groups do not contribute much to the outcome of these O-alkylation reactions. These results could serve as guidelines in planning synthetic strategies involving other carbohydrates and their derivatives.
New fluorescent probes reveal that flippase-mediated flip-flop of phosphatidylinositol across the endoplasmic reticulum membrane does not depend on the stereochemistry of the lipid

Glycerophospholipid flip-flop across biogenic membranes such as the endoplasmic reticulum (ER) is a fundamental feature of membrane biogenesis. Flip-flop requires the activity of specific membrane proteins called flippases. These proteins have yet to be i

Two-step conversions of myo-inositol into (±)-2,3,4,5,6- and 1,3,4,5,6-penta-O-benzyl-myo-inositols are described. Starting from these monohydroxy derivatives of myo-inositol, O-β-L-arabinopyranosyl-(1→2)-sn-myo-inositol from Japanese green tea, Camellia sinensis, and O-α-D-galactopyranosyl-(1→3)-sn-myo-inositol (galactinol) as well as its homolog, O-α-D-galactopyranosyl-(1→6(II))-galactinol, were synthesized by way of the in situ activating glycosylation procedure.
