A short and efficient route from myo - To neo -inositol

Wessig, Pablo,M?llnitz, Kristian,Hübner, Sebastian

, p. 1497 - 1500 (2010)

An efficient route from myo- to neo-inositol is described. The key steps of the sequence are oxidation of the hydroxy group at C-5 to the corresponding ketone, followed by a highly (dr = 7.8:1) stereoselective reduction. The route includes nine steps with an overall yield of 51% and is therefore superior to all hitherto reported methods for the preparation of neo-inositol. Georg Thieme Verlag Stuttgart New York.
