TextSentencer_T1 0-96 Sentence denotes Synthesis and X-ray structures of sulfate esters of fructose and its isopropylidene derivatives.
TextSentencer_T2 97-104 Sentence denotes Part 1:
TextSentencer_T3 105-222 Sentence denotes 2,3:4,5-di-O-isopropylidene-beta-D-fructopyranose 1-sulfate and 4,5-O-isopropylidene-beta-D-fructopyranose 1-sulfate.
TextSentencer_T4 223-409 Sentence denotes 2,3:4,5-Di-O-isopropylidene-beta-D-fructopyranose 1-sulfate have been synthesized by treatment of 2,3:4,5-di-O-isopropylidene-beta-D-fructopyranose with pyridine-sulfur trioxide complex.
TextSentencer_T5 410-526 Sentence denotes Direct hydrolysis of the isopropylidene group at C-4, C-5 gave 2,3-O-isopropylidene-beta-D-fructopyranose 1-sulfate.
TextSentencer_T6 527-733 Sentence denotes The crystal and molecular structures of ammonium (1a) and potassium (1b) salts of diisopropylidene derivative and ammonium (2) salt of monoisopropylidene derivative were determined by X-ray crystallography.
TextSentencer_T7 734-796 Sentence denotes Data for 1a and 1b were collected in 120 K and in 150 K for 2.
TextSentencer_T8 797-849 Sentence denotes All salts crystallized in P2(1)2(1)2(1) space group.
TextSentencer_T9 850-910 Sentence denotes There are three independent anions in asymmetric unit in 1b.
TextSentencer_T10 911-1104 Sentence denotes Pyranose rings in the diisopropylidene derivative salts studied adopt 2S(0) twist boat conformation, whereas in the monoisopropylidene exists in a slightly distorted chair conformation (4C(1)).
TextSentencer_T11 1105-1350 Sentence denotes A staggered conformation is preferred by the sulfate group as indicated by values of C-(ester)-S-O(terminal) torsion angles: -173.2(4) degrees in 1a, 175.1(6) degrees in anion A of 1b, 170.8(6) degrees in anion C of 1b and 177.9(2) degrees in 2.
TextSentencer_T12 1351-1510 Sentence denotes However, strong interactions such as potassium-oxygen and H-bonds may affect the geometry: in anion B of 1b the value of the torsion angle is 139.4(6) degrees.
