A novel synthesis of all stereoisomers of natural inositols has been developed. The key strategy is the stereoselective reduction of substituted β-hydroxy cyclohexanones, which are prepared from a variety of 6-O-acetyl 5-enopyranosides via Ferrier-II reaction catalyzed by palladium chloride. The utility of this approach is demonstrated by the synthesis of D-myo-inositol 1,4,5-tris(phosphate)(IP3).

The conversion of 6-O-acetyl-5-enopyranosides into fully oxygenated cyclohexanones was found to proceed efficiently with a catalytic amount of palladium chloride under neutral conditions. This method was proved to be superior in efficacy to the conventional Hg method. (C) 1998 Elsevier Science Ltd. All rights reserved.
