✦ Synopsis

f )-1,2:4,5-Di-0-isopropylidene-myo-inositol (11, C,2H,0,, crystallises in the mopoclinic space group, C2/c with unit-cell dimensions a = 22.587(3), b = 5.4204(3), and c = 22.174(4) A. (*)_1,2:5,6di-0-isopropylidene-myo-inositol (2), C,,H,O,, cOmtallises in the monoclinic space group, P2, /n with a = 11.543(3), b = 6.860(l), and c = 16.895(4) A. The inositol ring of 1 and 2 has a chair and skew conformation, respectively. Based on the crystalline conformations of 1 and 2, steric and hydrogen bonding features of the hydroxyl groups are discussed.
