The structures of the title compounds (2b and 3) have been investigated in the solid state by X-ray methods. The crystals of 2b are monoclinic, space group P2,, and of 3 orthorhombit, space grtup P2,2,2,. The cell dimensions are: for 2b, a = 9.910(2), b = 11;745W, c = 11.810(3) A, /3 = 97.32(l)"; a
An improved procedure for the preparation of 1,2-O-isopropylidene-nqVo-inositol is described. Racemic 1,4-di-O-benzyl-2,3-O-isopropylidene-myo-inositol was prepared by tinmediated benzylation of 1,2-0-isopropylidene-myo-inositol and resolved readily by crystalk sation of the o-camphanates. The use o
