[0044] Preparation of compound (I-3)

[0045]Add 0.5635g (2.34mmol) 3,4-dimethoxy-6-bromophenylacetylene, 0.4670g (3.11mmol) p-methoxyacetophenone, 0.3570g (3.18mmol) t-BuOK to the test tube reactor , 5 ml DMSO. Heated in an oil bath at 100°C for 1.5h. After the reaction, add water, extract with dichloromethane, combine the organic layers, and concentrate the residue to separate by column chromatography (eluent is petroleum ether: ethyl acetate = 10: 1), 0.2844g of the target compound was obtained, with a yield of 31%. M.p.133-134℃

[0046] Preparation of compound (I-4)

[0047] Add 0.2101g (2.06mmol) phenylacetylene, 0.3123g (2.08mmol) p-methoxyacetophenone, 0.2467g (2.20mmol) t-BuOK, 5mlDMSO into the test tube reactor. Heated in an oil bath at 100°C for 1.5h. After the reaction, add water, extract with dichloromethane, combine the organic layers, and concentrate the residue to separate by column chromatography (eluent is petroleum ether: ethyl acetate = 10: 1), 0.3272g ...

Embodiment 1

[0080] Embodiment 1: the preparation of compound (II-1)

[0081] Add β, γ-unsaturated ketone (I-1) (0.1840g, 0.7293mmol) and cesium carbonate (0.2796g, 0.7967mmol) into the reaction vessel, mix in 1,4-dioxane (2mL), Stir and react in an oil bath at 90°C for 13 hours; after the reaction, add water, extract with dichloromethane, combine the organic layers, and concentrate the residue to separate by column chromatography (eluent is petroleum ether: dichloromethane: = 1: 1, V:V), collect R f The eluate with a value of 0.3-0.35 was distilled under reduced pressure and dried to obtain the target compound (II-1), 0.0821 g, with a yield of 61.8%.

[0082] 1 HNMR (500MHz, CDCl 3 )δ7.79(dd, J=8.0,1.9Hz,1H),7.73-7.72(m,3H),7.62(d,J=8.8Hz,2H),7.56(d,J=8.0Hz,1H), 7.43(t, J=7.4Hz1H), 7.33-7.29(m, 4H), 7.23(t, J=7.4Hz, 2H), 7.19-7.16(m, 1H), 7.02(d, J=8.8Hz, 2H ),3.88(s,3H)

[0083]

Description

(1) Technical field [0001] The invention relates to a new class of terphenyl compound, its preparation and anti-tumor application. (2) Background technology [0002] Compounds containing terphenyl structures often have good biological activities in terms of immunosuppressive activity, antioxidant activity, neuroprotective activity, cytotoxic activity, and antithrombotic and anticoagulant activities. In addition, this kind of compound also performs well in terms of liquid crystallinity and electroluminescence, and is widely used in liquid crystal materials. At present, such compounds are mainly prepared by coupling reactions such as Ullmann, Suzuki, Stille, Kumada, etc., but this method has disadvantages such as using expensive metal catalysts. Therefore, it is of great theoretical significance and practical application value to develop new synthetic methods to prepare terphenyl compounds with novel structures. (3) Contents of the invention [0003] The present invention ...
