Embodiment 1
[0118] A kind of organic compound M1, the structure is as follows:
[0119]
[0120] The preparation method of this organic compound M1 comprises the steps:
[0121] (1)
[0122] Add compound A01 (30mmol) into a three-necked flask, stir and dissolve with 200mL tetrahydrofuran, protect with nitrogen, cool down to -78°C, then slowly add 15mL of 2M n-butyllithium (n-BuLi) solution dropwise, and stir for 0.5h after the addition. Then, a solution of compound B01 (30 mmol) in tetrahydrofuran (THF) was dropped into the reaction solution. After dropping, warm up to room temperature, stir for 2 h, add saturated ammonium chloride solution to quench, add water, concentrate the organic phase to obtain an oil, add 100 mL of acetic acid and 20 mL of HCl to the oil, and stir to reflux for 12 h. After cooling, saturated brine was added and extracted with dichloromethane to obtain an organic phase. The organic phase was washed three times with water. The solvent was removed by evapora...

[0127] A kind of organic compound M19, the structure is as follows:
[0128]
[0129] The preparation method of this organic compound M19 comprises the steps:
[0130]
[0131] In a 250mL round bottom flask, M01-1 (10mmol), C19 (12mmol) and Na 2 CO 3 (80mmol) were added to toluene / EtOH / H 2 In O (75 / 25 / 50, mL) solvent, a mixed solution was formed, and then Pd(PPh 3 ) 4 (0.48mmol) was added in the above-mentioned mixed solution, and the intermediate obtained by reflux reaction for 20h under a nitrogen atmosphere was cooled to room temperature, added to water, then filtered through a diatomaceous earth pad, extracted with dichloromethane simultaneously, then washed with water, and After drying over anhydrous magnesium sulfate, filtration and evaporation, the crude product was purified by silica gel column chromatography to obtain the target product M19.
[0132] The elemental analysis result of organic compound M19 (molecular formula C 55 h 35 B 2 NO): theoretical v...
Embodiment 3
[0134] An organic compound M39 with the following structure:
[0135]
[0136] The preparation method of this organic compound M39 comprises the steps:
[0137] (1)
[0138] 50 mmol B39 was dissolved in 250 mL THF, 50 mmol A39 was dissolved in 750 mL THF, the solution of B39 was added dropwise to the solution of A39, and the resulting mixture was stirred at room temperature for 16 h. After removing the solvent under vacuum, the residue was dissolved in 250 mL of dichloromethane, washed three times with 200 mL of distilled water, dried over sodium sulfate, the organic phase was evaporated, and the residue was recrystallized five times with dioxane to obtain compound M39- 1.
[0139] (2)
[0140] In a 250mL round bottom flask, M39-1 (10mmol), C01 (12mmol) and Na 2 CO 3 (80mmol) were added to toluene / EtOH / H 2 In O (75 / 25 / 50, mL) solvent, a mixed solution was formed, and then Pd(PPh 3 ) 4 (0.48mmol) was added in the above-mentioned mixed solution, and the intermedia...
