Syntheses of D-chiro-3-inosose and (+)-D-chiro inositol

There are described novel biocatalytic and chemical processes for the synthesis of various oxygenated compounds. Particularly, there are described processes for the synthesis of a useful synthon 12 made by reacting a protected diol (acetonide) with permaganate under appropriate conditions. Such synthon is useful of the synthesis of various pharmaceutically important compounds such as D-chiro-inositol and D-chiro-3-inosose. Also, there are disclosed novel compounds, including specifically the synthon 12 and compounds derived therefrom.
