YieldReaction ConditionsOperation in experiment
89% With tetrabutylammomium bromide; sodium carbonate; In water; at 100℃; for 1h;Green chemistry; General procedure: A mixture of the corresponding bromochromone1(0.50 mmol), the corresponding boronic acid2(0.60 mmol), Na2CO3(0.50 mmol) andPdSILP(0.05% mmol of Pd) in H2O was stirred under ohmic heating at 100 C for 1 h. The catalyst was filtered-off and the filtrate was extracted with Et2O (3 × 10 mL). The combined extracts were dried over Na2SO4and evaporated under reduced pressure affording products3. The physical data of known isoflavones3a-fwere comparable to those of the literature [34,35,36,37,38]. The physical data of the new isoflavones3g-jare shown below.

YieldReaction ConditionsOperation in experiment
78% In chloroform; at 80℃; for 1.5h; Piperazine (840.20 mg) was dissolved in chloroform,Stir in a 25 mL round bottom flask.Compound b (1.10g) was slowly added. After the addition, it was placed in an oil bath and heated to 80 C for 1.5 h. The reaction was analyzed by thin layer chromatography and under UV light. After the reaction was completed, it was reduced to room temperature. Concentrated by pressure, using silica gel chromatography column with dichloromethane:methanol=10:1 Separation and purification were carried out to obtain Compound c, an orange solid, yield 78%.

YieldReaction ConditionsOperation in experiment
88% With copper(l) iodide; potassium tert-butylate; In N,N-dimethyl-formamide; at 25℃; General procedure: A round-bottom flask with a magnetic bar was charged with the appropriate3-bromoflavone (1 mmol), KOt-Bu (3 mmol, 3 equiv), DMF(4 mL), the corresponding aniline (1.5 mmol) or N-phenylurea (2mmol) with CuI (5 mol%). The reaction mixture was stirred at r.t. untilthe complete consumption of the starting material (TLC monitoringwith 10% hexane and EtOAc). The reaction mixture was poured intocrushed ice, the precipitate formed was collected by suction filtrationand purified by column chromatography to give the required product 2a-5d, respectively, in excellent yield.
