A variety of inositol phosphates including myo-inositol 1,4,5-trisphosphate, which is a secondary messenger in transmembrane signaling, were selectively synthesized via Yb(OTf)3-catalyzed desymmetrization of myo-inositol 1,3,5-orthoformate using a proline-based chiral anhydride as an acylation precursor. The investigated catalytic system could regioselectively differentiate the enantiotopic hydroxy groups of myo-inositol 1,3,5-orthoformate in the presence of a chiral auxiliary. This key step to generate a suitably protected chiral myo-inositol derivatives is described here as a unified approach to access inositol phosphates.

Herein, we report the development of two fluorescent sensors for inositol 1,4,5-trisphosphate (InsP3), containing either two free cyclen or zinc(II)/cyclen groups preorganized into a binding cleft. Preorganization was achieved using a rigid acr

The synthesis of d-myo-inositol 1,4,5-trisphosphate (InsP3) from methyl α-d-glucopyranose, via a type 2 Ferrier rearrangement is reported. A key intermediate in this synthesis possesses orthogonal protecting groups at the 1-, 4- and 5-position, making it a versatile starting point for the synthesis of unnatural InsP3 derivatives. Biological evaluation of the synthetic InsP3 demonstrates that this compound evokes selective Ca2+ release via activation of InsP3 receptors.

Synthetic routes to various inositol polyphosphates have been discovered utilizing catalytic enantioselective and site-selective phosphorylation reactions. The syntheses described herein exploit a common intermediate to gain efficient access to eight unique inositol polyphosphates.
Regioselective phosphorylation of vicinal 3,4-hydroxy myo-inositol derivative promoted practical synthesis of D-PtdIns(4,5)P2 and D-Ins(1,4,5)P3

The reactivity of 3 and 4-OH in 3,4-diol myo-inositol derivatives were observed through the phosphorylation, acylation and silylation. The results indicated that 3-OH is much more reactive than 4-OH, giving regiospecifically 3-mono-functionalized products

Optically active myo-inositol 1,4,5-tris(dihydrogen phosphate) 1, which has now been recognized as a second messenger in a new intracellular signal transduction system, has been prepared starting from myo-inositol.The key step, phosphorylation of an adequately protected polyhydroxy derivative, was accomplished by three methods, among which a phosphoramidite method using a new phosphitylating agent, o-xylylene N,N-diethylphosphoramidite, gave the triphosphoric ester in quantitative yield.Optical resolution was effectively realized by derivatization into diastereoisomeric l-menthoxyacetic esters.NMR spectra and optical rotation are shown to depend on the pH of an aqueous solution of compound 1.

Partial benzoylation of the 3,4-dibenzyl ethers of D- and L-chiro-inositol provided the 1,2,5-tri-O-benzoyl-3,4-di-O-benzyl-chiro-inositols. Inversion of the free axial hydroxyl group gave a mixture of chiral 1,3,4- and 1,2,4-tri-O-benzoyl-5,6-di-O-benzyl
