Decitols

It is evident that syntheses of the Lespieau type can lead to a great number of polyhydroxy compounds. Wiemann has prepared compounds such as CHsCH2(CHOH)6CH2CH3, which he calls diethyl mannitol. It would seem better to designate this substance a tetra-desoxy decitol or decane hexol since its configuration is not known with certainty. Apparently this type of synthesis leads to symmetrical arrangements of hydroxyl groups, since allitol, dulcitol and D,L-mannitol are the only hexitols that were identified as products. 

Four octitols, one nonitol, one decitol, and one dodecitol have been de-described. Of these only the configurations of the octitols are completely known. None occurs naturally.
