Highly direct total syntheses of phosphatidylinositol (PI), phosphatidylinositol-3-phosphate (PI3P), phosphatidylinositol-3,5-bisphosphate (PI3,5P2), and a range of deoxygenated versions are reported. Each synthesis is carried out to deliver the target in optically pure form. The key step for each synthesis is a catalytic asymmetric phosphorylation reaction that affects desymmetrization of an appropriate myo-inositol precursor. Elaboration to each target compound is then carried out employing a diversity-oriented strategy from the common precursors. In addition to three natural products, several additional streamlined total syntheses of deoxygenated PI analogues are reported. These syntheses set the stage for high-precision biological investigations of polar headgroup/biological target interactions of these membrane-associated signaling molecules.
