Rapid and efficient routes to phosphatidylinositol 3,4,5-trisphosphates via myo-inositol orthobenzoate

Efficient routes to two phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P3] analogues with different acyl chains have been developed by using cheaply available myo-inositol as the starting material. The high yield of the orthobenzoate derivative, preferential formation of the required protected inositol diastereomer in its desymmetrization and ease of separation make the synthesis expedient, economical and high yielding. Due to the inherent problem of racemization of diacylglycerol (DAG), the synthesis of phosphatidylinositol phosphates [PIPns] with unambiguous stereochemical purity has always been difficult. Our methodology excludes the possibility of racemization in the DAG unit and thus provides access to PtdIns(3,4,5)P3 of high optical purity. Since the acyl functionalities are introduced last, the methodology reported is amenable to the synthesis of PtdIns(3,4,5)P3 with any acyl chain (or even a library of analogues).

Asymmetric Total Synthesis of Phosphatidylinositol 3-Phosphate and 4-Phosphate Derivatives

New asymmetric syntheses of phosphatidylinositol 3-phosphate (PtdIns(3)P) and phosphatidylinositol 4-phosphate (PtdIns(4)P) derivatives are described. Key intermediates were used to prepare diacylglyceryl moieties with dibutyryl, dioctanoyl, and dihexadecanoyl chains. In addition, a modified route provided PtdIns(3)P and PtdIns(4)P triesters with P-1-linked aminopropyl groups for preparation of affinity probes. The synthesis of the inosityl precursor employed a dibutyltin oxide-mediated p-methoxybenzyl (PMB) etherification to give either the 2-PMB- or the 3-PMB-protected glucopyranosides. The Ferrier rearrangement was used to convert suitably protected glucose derivatives to enantiomerically pure, differentially protected D-myo-inositol key intermediates. A versatile phosphoramidite reagent was employed to allow synthesis of PtdInsPn derivatives with diacylglyceryl moieties of different chain lengths.
