1-(2-Hydroxy-4-(methoxymethoxy))-3-methylacetophenone (25) 1-(2,4-Dihydroxy-3-methylphenyl)ethanone (6.00 g, 36.1 mmol) (24) was dissolved in DCM (110 mL, 0.330 M) to give an orange solution. DIPEA (15.9 mL, 95.5 mmol) was added causing the solution to turn a deep red color. Technical grade MOMCl (5.50 mL) was added, at, which time the solution turned yellow. The solution was allowed to stir at RT for 18 h before being quenched with H2O. The aqueous layer was extracted with DCM (2*30 mL). The organic fractions were washed once each with NaHCO3, brine, then dried over MgSO4 and concentrated. The crude product was purified by Biotage flash column chromatography, eluting with 30% EtOAc-Hexanes on a 100 g cartridge to afford (25) (7.14 g, 34.0 mmol, 94%) as white needles.

The suspension is treated successively with pyridine (4.4 ml, 54 mmole) and N,N, dimethylamino-pyridine (730 mg, 6 mmole) and the solution is cooled to 0 C. Triflic anhydride (11 ml, 66.2 mmole), in 1*100 ml dichloromethane, is added slowly dropwise to the reaction mixture (30 min). The reaction is stirred for 1 h at room temperature for 1 h and the mixture is washed with 2*200 ml 5% hydrochloric acid. The organics are dried over magnesium sulfate and are concentrated in vacuo to a yellow oil. The oil is distilled via kugelrhor under high vacuum (165 C) to provide 16.4 (91%) of triflate as a white solid. Melting Point: 60-64 C.

General procedure for the solid-phase synthesis of 2'-hydroxychalcones and flavanones (1-33) General procedure: In a 24 reaction vessels of Büchi Syncore synthesizer a mixtureof 2'-hydroxyacetophenones (10 mmol), DIEA (2 mmol) and 2-chlorotritylchloride resin (1.0-1.5 mmol Cl/g) in anhydrous CH2Cl2/DMF (3:0.5 mL) was stirred at room temperature under nitrogen atmosphere for 48 h to provide the solid-supported acetophenones.These immobilized acetophenones were washed with anhydrous THF (2 × 3 mL), anhydrous MeOH (3 × 3 mL) and anhydrous CH2Cl2 (4 × 3 mL) and dried under vacuum for 24 h. To the solid-supported acetophenones (1 mmol) were added the appropriate benzaldehydes (10 mmol), a solution of 4% NaOH in anhydrous MeOH (2 mmol) and anhydrous THF (3 mL). The reaction mixture was gentle stirred at room temperature under nitrogen atmosphere for 48 h to give the solid-supported chalcones. These immobilized chalcones were washed and dried in the same sequence as the first step described above. The solid-supported chalcones were exposed to 2% TFA in CH2Cl2 at room temperature under nitrogen atmosphere for 30 min. The cleaved 2-chlorotrityl resin was filtered and washed with 2% TFA:CH2Cl2 (2 × 1 mL) and CH2Cl2 (5 × 3 mL) and the solvent was evaporated under reduced pressure. The resulting residue was then purified by flash chromatography cartridges (SiO2, n-hexane:EtOAc) to afford the 2'-hydroxychalcones 1-31 and flavanones 32 and 33.

72% Stage #1: 1-(2,4-dihydroxy-3-methylphenyl)ethanone With lithium hexamethyldisilazane In tetrahydrofuran at -78℃; for 3.3h; Inert atmosphere; Cooling with ice; Stage #2: Diethyl carbonate In tetrahydrofuran at 20℃; Inert atmosphere; Cooling with ice; 4.2. General procedures for syntheses of ethyl 3-(2-hydroxyphenyl)-3-oxopropanoates (1a-1s) General procedure: Under a dry argon atmosphere, lithium bis(trimethylsilyl)amide (1 M, 3 mmol) was cooled 78 C and a mixture of 2-hydroxyacetophenone (136 mg, 1 mmol) in dry THF (2 mL) was added dropwise to the above solution in 20 min. The reaction solution was stirred at 78 C for 1 h and in ice-bath for 2 h, and then a solution of diethyl carbonate (127.4 mg, 1.08 mmol) in dry THF(1 mL) was rapidly added to the above mixture in ice-bath for 3-4 h. Then, the mixture was stirred at room temperature. After 2-hydroxyacetophenone had disappeared completely, the reaction solution poured into a mixture of concentrated HCl (1.5 mL) and ice (20 g). The mixture was extracted with CHCl3. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The crude products were purified using column chromatography on silica gel to give 1a in good yields, and 1b-1s were prepared with the same method.
