YieldReaction ConditionsOperation in experiment
32.4% With palladium on activated charcoal; hydrogen; In methanol; at 20.0℃; General procedure: 2,4-Dihydroxyacetophenone was dissolved in dry THF, and the mixture was cooled to -60 C under an atmosphere of dry nitrogen. LiHMDS (1.6M in hexane, 30mmol) was added dropwise, and the reaction was stirred for 45min at -30 C. The phenolic hydroxyl groups of 3,4-dihydroxybenzoic acid ethyl ester (1.82g, 10mmol) were protected by benzyl (RY3-c) and dissolved in dry THF (20mL). The mixture was then cooled to -60 C and to 4.36g of RY3-c, and dry THF (40mL) was added dropwise. This mixture was stirred for another 45min at -60C and then incubated at room temperature overnight. The reaction mixture was poured on ice and acidified with 2.0M HCl. The THF was removed, the crude 1-(3,4-bis-benzyloxy-phenyl)-3-(2,4-dihydroxy-phenyl)-propane-1,3-dione was dissolved in 2-propanol (50mL), 0.5g Dowex W50×8 (H+ form) was added, and the reaction was heated under reflux for 24h under an atmosphere of dry nitrogen. The solids were filtered, and then the reaction mixture was poured on water. The solids were filtered and dissolved in MeOH (50mL), and Pd-C (1g) was added under an atmosphere of dry hydrogen at room temperature overnight. The solids were filtered and MeOH was removed. Purification of the crude product by flash chromatography (30% EtOAc/hexane) yielded RY3-c (1.28g, 32.4%) as a white solid. RY3-c: 1HNMR (500MHz, DMSO-d6): δ 6.62 (s, 1H), 6.92 (m, 2H, J=10Hz), 6.95 (d, 1H, J=5Hz), 7.40 (dd, 2H, J=10Hz), 7.88 (d, 1H, J=10Hz), 9.61 (s, 2H), 10.77 (s, 1H). 13CNMR (126MHz, DMSO-d6): δ102.83, 104.97, 113.66, 115.24, 116.47, 118.99, 122.62, 126.94, 146.16, 149.61, 157.81, 163.02, 163.07, 176.63.

YieldReaction ConditionsOperation in experiment
38% 2.4 Synthesis of [Ru(II)([9]aneS3)(S-DMSO)(<strong>[2150-11-0]7,3',4'-trihydroxyflavone</strong>)] (1) A solution of thflv (94.5 mg, 0.35 mmol) in refluxing ethanol (15 mL) was treated with one equivalent of tetrabutylammonium hydroxide (350 μL, 0.35 mmol). The colour of the solution changed from light yellow to orange. After 20 min, the complex [Ru([9]aneS3)Cl2(DMSO)] (150 mg, 0.35 mmol) was added and the reaction mixture was left under reflux for 48 h ( Scheme 1 ). During this time the solution became dark orange and a dark green precipitate was formed. The hot solution was cannula-filtered and the remaining solid was washed with ethanol (20 mL), diethyl ether (20 mL) and dried (90 mg, 38% yield).
