Embodiment 1
[0072] Embodiment 1: raw material
[0073] Preparation method: Under nitrogen atmosphere, the raw material 2-[hydroxyl (phenyl)methyl]-1-phenylcycloprop-2-ene-1-carboxylic acid (2.66g, 0.01mol) and boron trifluoride tetrahydrofuran complex Compound (2.8g, 0.02mol) was mixed uniformly in 15ml of ethylene glycol dimethyl ether, and reacted at room temperature for 12 hours. The obtained mixed solution was dried under reduced pressure at 40° C. and a vacuum degree of about -0.1 MPa to remove the solvent to obtain an intermediate. Dissolve lithium ethoxide (1.04g, 0.02mol) in 10ml of ethanol and slowly add it to the intermediate, stir and react at 45°C for 8 hours, and dry the resulting mixture under reduced pressure at 45°C and vacuum degree of about -0.1MPa , The obtained solid was washed three times with n-butyl ether, filtered and dried to obtain the product M1. Yield was 76%, NMR as figure 1 shown.
Embodiment 2
[0074] Embodiment 2: raw material
[0075] Preparation method: Under argon atmosphere, the raw material 3,4-dihydroxy-3-cyclobutene-1,2-dione (1.14g, 0.01mol) and boron trifluoride etherate complex (2.98g, 0.021 mol) in 15ml THF (tetrahydrofuran), mixed uniformly, and reacted at room temperature for 12 hours. The resulting mixed solution was dried under reduced pressure at 30° C. and a vacuum of about −0.1 MPa to remove the solvent to obtain an intermediate. Add 14ml of butyllithium hexane solution (c=1.6mol / L) to the intermediate, stir and react at room temperature for 6 hours, and dry the resulting mixture under reduced pressure at 40°C and a vacuum of about -0.1MPa. The obtained crude product was washed 3 times with cyclohexane, filtered and dried to obtain the product M2. The yield was 87%, NMR such as figure 2 shown.
Embodiment 3
[0076] Embodiment 3: raw material
[0077] Preparation method: Under a nitrogen atmosphere, take a certain amount of raw materials cis-(1S,2R)-3-methyl-3,5-cyclohexadiene-1,2-diol (1.26g, 0.01mol) and methanol Lithium (0.76g, 0.02mol) was mixed evenly with 20ml of methanol, and reacted at room temperature for 8 hours. The obtained mixed solution was dried under reduced pressure at 40° C. and a vacuum degree of about -0.1 MPa to remove the solvent to obtain an intermediate. Boron trifluoride tetrahydrofuran complex (3.07g, 0.022mol) and 15ml THF (tetrahydrofuran) were added to the intermediate, stirred at room temperature for 6 hours, and the resulting mixture was placed at 40°C and a vacuum of about -0.1MPa Drying under reduced pressure, the obtained solid was washed three times with isopropyl ether, filtered and dried to obtain the product M3. Yield 76%, NMR as image 3 shown.
