Garegg, Per J.,Lindberg, Bengt,Kvarnstroem, Ingemar,Svensson, Stefan C. T.
, p. 205 - 216 (1988)
The 1D and 1L forms of 1,2,4,5,6- and 1,2,3,4,5-penta-O-methyl-myo-inositol have been prepared from the corresponding chiral mono-O-benzyl derivatives.Convenient preparations are also described of achiral derivatives of 1-, 2-, 4-, and 5-O-benzyl-myo-inos
