Embodiment 1
[0058] Example 1 : 3-O-methyl-D-inositol-5-(1'-(1',2',4'-triazole)) nucleoside and 3-O-methyl-D-inositol-4 Synthesis of -(1'-(1', 2', 4'-triazole)) nucleosides (compound numbers 1a and 1b, respectively)
[0059] (1) Synthesis of 1,2:5,6-di-O-isopropylidene-3-O-methyl-D-inositol
[0060] After adding 25mLDMF, 50mL 2,2-di-methoxypropane and 150mL acetone in a 500mL three-necked flask, add 10.0g (51.5mmol) of 3-O-methyl-D-inositol, 380mg of p-toluenesulfonic acid ( 2.0mmol) and anhydrous magnesium sulfate 9.0g, the suspension was stirred at room temperature for 16 hours, 1.0g of sodium bicarbonate was added, stirred for half an hour and then filtered, the filter residue was washed 3 times with ethyl acetate and combined with the filtrate, concentrated under reduced pressure Recrystallize with a mixed solvent of n-hexane and ether in equal proportions to obtain 12.6 g (46.0 mmol, 89%), the crude product can be directly used in the next step reaction. Melting point: 95-96°C, [α...
Embodiment 2
[0071] Example 2 : 3-O-methyl-D-inositol-5-(9'-(5'-nitroindazole)) nucleoside and 3-O-methyl-D-inositol-4-(9'- Synthesis of (5'-nitroindazole)) nucleosides (compound numbers 2a and 2b, respectively)
[0072] (1) Synthesis of 1,2:5,6-di-O-isopropylidene-3-O-methyl-D-inositol
[0073] Synthesized as in Example 1 (1) method and conditions.
[0074] (2) Synthesis of 1,2:5,6-di-O-isopropylidene-3-O-methyl-4-methanesulfonyl-D-inositol
[0075] Synthesize as embodiment 1 (2) method and condition.
[0076] (3) Synthesis of 3-O-methyl-4-methanesulfonyl-D-inositol

[0081] Add 352mg (2mmol) of epoxy compound and 489mg (3m...
Embodiment 3
[0085] Example 3 : Synthesis of 3-O-methyl-D-inositol-5-(1'-(1',2',4'-triazole)) nucleoside fumaric acid complex (1c)
[0086]The synthetic method of 3-O-methyl-D-inositol-5-(1'-(1', 2', 4'-triazole)) nucleoside fumaric acid complex (1c) is as follows: 3- O-methyl-D-inositol-5-(1'-(1',2',4'-triazole)) nucleoside 245mg (1mmol) and fumaric acid 124mg (1mmol) and 2ml isopropanol Mixed, the resulting mixture was stirred at 50°C until the solids were completely dissolved, then cooled at room temperature to precipitate crystals, filtered to obtain the solids, washed with ether, and dried in vacuo to obtain 269 mg, with a yield of 73%. 1 In addition to 3-O-methyl-D-inositol-5-(1'-(1',2',4'-triazole)) nucleoside signal in H NMR (DMSO), in δ(ppm) 6.185 (s, 2H) shows the signal of fumaric acid double bond hydrogen.
