Optically pure 6-deoxy-inososes, 6-deoxy-inositols and 6-deoxy-inositol-1,4,5-trisphosphates were synthesized from D-galactose by the carbohydrate-inosose Ferrier rearrangement. 6-Deoxy-inositolphosphates exhibit a tight binding to the Ins-P3-receptor making such compounds an interesting tool for studying the intracellular signalling.
