Embodiment 1
[0060] Synthesis of Example 1 Compound 1:
[0061]
[0062] Dissolve 0.01 mol of reactant A-1 and 0.012 mol of reactant B-1 in 150 mL of toluene, add 0.015 mol of potassium tert-butoxide, and react at 120 °C for 24 hours under a nitrogen atmosphere. , cooled and filtered, the filtrate was rotary evaporated to remove the solvent, and the crude product was passed through a silica gel column to obtain compound 1, the yield was 77.6%, and the HPLC purity was 99.49%; elemental analysis of the structure (C 58 H 39 N) Theoretical: C, 92.89; H, 5.24; N, 1.87; Tested: C, 92.87; H, 5.21; N, 1.88. MS(m / z)(M+): Theoretical value is 749.31, and the found value is 749.29.
Embodiment 18
[0063] Synthesis of Example 18 Compound 214:
[0064]
[0065] Dissolve 0.01 mol of reactant A-11 and 0.012 mol of reactant B-15 in 150 mL of toluene, add 0.015 mol of potassium tert-butoxide, and react at 120 °C for 24 hours under a nitrogen atmosphere. After the reaction was completed, it was cooled and filtered, the filtrate was rotary evaporated to remove the solvent, and the crude product was passed through a silica gel column to obtain compound 214; the yield was 88.3%, the HPLC purity was 99.14%, and the elemental analysis structure (molecular formula C 62 H 41 NO) Theoretical: C, 91.26; H, 5.06; N, 1.72; O, 1.96; Tested: C, 91.27; H, 5.05; N, 1.71; O, 1.97. MS(m / z)(M+): Theoretical value is 815.32, and the found value is 815.33.
Embodiment 16
[0066] The synthesis of compound A-15 in Example 16 is as follows:
[0067]
[0068] Dissolve 0.02mol of raw material C-1 with 60mL of dry THF, keep at -78°C for 30min, add 24mL of 1.2M n-butyllithium solution under a nitrogen atmosphere, stir for 1 to 2 hours, and under a nitrogen atmosphere Continue to add 0.02mol of raw material D-1, stir evenly, slowly raise to room temperature, continue stirring reaction at room temperature for 10-24 hours, add 20 mL of water to the reaction system, continue stirring for 1-2 hours, the product is precipitated from the reaction system, Filtration to obtain intermediate I-1 with HPLC purity of 91.89% and yield of 84.9%; 0.02 mol of intermediate I-1 was dissolved in a mixture of 50 mL of acetic acid and 5 mL of hydrochloric acid, stirred and heated to 110 °C, reacted for 10 h, and cooled naturally. After reaching room temperature, the product was precipitated, filtered and washed with water and methanol to obtain reactant A-15, HPLC purit...
