VISCUMITOL, A DIMETHYL-ETHER OF MUCO-INOSITOL FROM VISCUM ALBUM
Richter, Andreas
, p. 3925 - 3928 (1992)
A new di-O-methyl-inositol, named viscumitol, was isolated from Viscum album and the structure established by chemical and spectroscopic means as 1,2-di-O-methyl-muco-inositol.In V. album and other members of the Viscaceae, this cyclitol was stored in high concentrations up to 8.7percent dry weight.Possible physiological functions and chemotaxonomic aspects are briefly discussed. Key Word Index: Viscum album; Viscaceae; cyclitol; 1,2-di-O-methyl-muco-inositol; viscumitol.

The intramolecular aldol condensation of aldohexos-5-ulose derivatives of the D-xylo and L-ribo stereoseries has been studied. Only one of the four possible inososes was isolated from both stereoseries in reasonable yields (30-38%). The results obtained, together with the previous findings for the L-arabino and L-lyxo stereoseries, allowed for the rationalisation of a mechanism of the reaction based on open-transition-state models and electron-withdrawing inductive effects. Complementary reductions of the intermediate inososes were possible by changing the reaction conditions, and two isomeric inositol derivatives were obtained with complete stereoselection from each inosose. The presented approach permits us to control the configuration of three out of the six stereocentres of the inositol frame and gives access to seven of the nine inositols. Noteworthy, for the D-xylo derivative, the two-step sequence (condensation followed by reduction with NaBH(OAc)3) represents the biomimetic synthesis of myo-inositol. Furthermore, the sugar-based pathway leads directly to enantiomerically pure selectively protected inositols and does not require any desymmetrisation procedure which is needed when myo-inositol and other achiral precursors are employed as starting materials. As an example of application of the method, the indirect selective protection of secondary inositols' hydroxy functions, by placing specific protecting groups on the aldohexos-5-ulose precursor has been presented.

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 permanganate 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.
Inositol synthesis: Concise preparation of L-chiro-inositol and muco- inositol from a common intermediate

, p. 2011 - 2014 (2007/10/03)
Fully stereoselective large-scale syntheses have been attained for L- chiro-inositol (2) and muco-inositol (3) by means of controlled peripheral oxygenation of cyclohexadiene diol 1.
