[Abstract]:In this paper, the structure modification of nucleoside drugs and nucleoside compounds was reviewed, and then the synthesis of spiroside from D- glucose was studied. Wittig reaction, Michael addition reaction, Mannich reaction and Henry reaction were used. The progress of stereoselective synthesis of a series of glucospironoside analogues is as follows: first, using D-glucose as raw material, After two steps of reaction, sugar oxide 1 was obtained, then compound 3 was obtained by Wittig reaction and Michael addition reaction. Finally, the glucospironoside compound 4H5, 6, 7, 7, 8, 10 was obtained by the Mannich reaction of compound 3. Of these, 6 and 7, 8 and 9 were CH3COCH3, concentrated H _ 2SO _ 4 dried by stereoisomer. (a), respectively, and (b) PDC, DCM, Ac2O; (c) Wittig reagent, CHCl3; (d) CH3NO2,DBU; (e) HCHO, C _ 2H _ 5OH, R-NH2 _ 2, were used as raw materials for D- glucose. After four steps of reaction, saturated nitrocompound 11 was obtained, and then the 6 hydroxyl. (a) dried CH3COCH3, concentrated H _ 2SO _ 4 was protected by Ts, and (b) PDC, DCM, Ac2O; (c) CH3NO2, THF, KF; (d) CH3OH,H2O, acetic acid; (e) TsCl, Py _ 3 was used as raw material for D- glucose. The unsaturated nitro compound 13 was obtained by multistep reaction, then compound 14 was obtained by Michael addition reaction. Finally, the compound was protected by hydroxyl deprotection. (a) DMSO, Ac2O; (b) CH3NO2, anhydrous THF, NaH; (c) CH3OH, H 2O and acetic acid; (d) TsCl, Py in this thesis, 18 compounds were synthesized, 13 of which were new compounds. The structure of the new compound was characterized by 1H NMR,13C NMR,HR-MS,IR et al.
