Embodiment 1
[0046] This example provides an aryl ketone compound, the structural formula of which is shown in A1,
[0047]
[0048] The preparation method of this compound is as follows:
[0049]
[0050] S1. Weigh binaphthol, cesium carbonate, 4,4-difluorobenzophenone and dissolve them in N,N-dimethylformamide in a 100mL round bottom flask at a molar ratio of 1:2:1. Under the condition of nitrogen protection, the above reactant was heated to 100° C. and reacted for 10 h. After the reaction was completed, the reaction liquid was cooled to room temperature, and extracted three times with ethyl acetate and saturated brine. The organic phase was taken, and the crude product was obtained after evaporating ethyl acetate under reduced pressure. Then, through silica gel column chromatography, using ethyl acetate / n-hexane as eluent, separation and purification are carried out to obtain intermediate 1, the structural formula of which is as follows
[0051]
[0052] S2. In a 100mL round...
