Synthesis of 2-deoxy-2-fluoro-phosphatidylinositol-4,5-bisphosphate and analogues: Probes and modulators of the mammalian PI-PLCS

An approach to synthesis of 2-modified phosphatidylinositol-4,5-bisphosphates, which are substrate analogues useful as probes and modulators of the PI-PLC enzyme family, is described and illustrated for the dibutyl-2-deoxy-2-fluoro analogue, a probe designed for delineating substrate and PI-PLC interactions by X-ray crystallography.
