The dianions 3, 4, and 16, which are suitable for nucleophilic addition to aldehydo-saccharides, can be obtained by reaction of 1,3-dithiane-2-methanol, or the appropriate side chain-elongated derivatives, with 2 molar equivalents of butyllithium.With these dianions, chain elongated saccharides can be made and, in one step, various potential chiral centres may be introduced.The octose 18, the decose 21, and the undecose 22 are obtainable from 17.With 23, the elongation of the chain leads to the septose 25, the nonose 27, and the decose 28.A 2-septulose 35 and 5-deculose 37 were also made.
