100% | With oxalyl dichloride In dichloromethane at 20℃; | 3-Phenylpropanoyl chloride (74). A 200 mL flask fitted with a stir-bar and septum with an Ar inlet was charged with hydrocinnamic acid (5.00 g, 33.3 mmol), DMF (0.1 mL), and CH2CI2 (30 mL). To the resultant solution was added (COCI)2 (2M in CH2CI2, 20.0 mL, 40.0 mmol) over 30 min. The mixture stirred overnight at rt, and then was concentrated in vacuo to give 5.9 g of 74 as a yellow oil (100percent). HPLC analysis (15:10:75 H2O:A1 :MeOH) showed a purity of 99percent with a retention time of 5.3 min. |
100% | With oxalyl dichloride In dichloromethane for 24 h; Inert atmosphere | To a stirred solution of 3-phenylpropanoic acid (3.0 g, 20 mmol, 1 eq.) in anhydrous CH2Cl2 (165 mL) under nitrogen was added oxalyl chloride (16.5 mL 190 mmol, 10 eq.) rapidly via syringe. The reaction mixture was stirred for 24 h, after which the solvent and unreacted oxalyl chloride were Removed by distillation under reduced pressure. The resulting yellow liquid was concentrated via azeotrope with benzene (3 x 50 mL) in vacuo and dried under a vacuum to yield 37 (3.4 g, ~100percent) as a yellow liquid, which was used directly in the next step. |
95% | With thionyl chloride In benzene for 4 h; Reflux | Dihydrocinnamic acid (10b) (3.0g, 0.02mol) was dissolved in dry benzene (5mL, 0.06mol) at room temperature then SOCl2 (10mL, 0.14mol) was added in a dropwise manner. The reaction mixture was allowed to heat at reflux for 4h. The solvent was evaporated under reduced pressure to give (3.4g, 95percent) of 11b as yellow oil. The crude product was used in the next step without further purification or characterization. |

(i) A soln of 3-phenyl-propionyl chloride (2.0 mL; 13.5 mmol) in dry THF (50 mL) was added over 6 min to a 0 °C soln of diazomethyl-trimethyl-silane (2.0 M in hexanes; 15 mL; 30 mmol) in dry THF (50 mL). After 3 h, the rxn was coned to a liquid, (ii) Aq. HBr (48percent; ca. 2.5 eq) was added in one portion to a soln of this crude material in AcOH (30 mL) at 0 °C. After 10 min the rxn was coned. EtOAc (50 mL) was added and the soln washed with water (2 x 15 mL), satd NaHCO3 (3 x 15 mL), water (1 x 15 mL) and satd NaCl (2 x 15 mL). After drying over MgSO4, filtering through a pad of silica with an EtOAc wash and coned to an oil, the crude material was purified by MPLC (SiO2 with a 0 - > 20percent EtOAc in hexanes gradient) yielding bromomethyl ketone as an off-white solid (1.977 g; 65percent). IH NMR (CDC13) δ 7.37 - 7.18 (m, 5H), 3.85 (s, 2H), 3.01 - 2.94 (m, 4H); GC-MS 226/228 ([M]+). |
