1-(3-溴苯基)硫烷基丙-2-one

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1(3-Bromo-phenylsulfanyl)-propan-2-one (4.0 g, 16.3 mmol) was dissolved in MeOH:DMF (1:1, 100 mL) and N2 (g) was bubbled through the solution for 5 minutes. Triethylamine (5.7 mL, 40.8 mmol) and (1,1′-bis(diphenylphosphino)ferrocene)-dichloropalladium(II) (0.600 g, 0.82 mmol) were added then CO (g) was bubbled into the reaction mixture for five minutes. The reaction was kept under CO atmosphere and heated to 80° C. overnight. The reaction was worked up then filtered through a plug of silica gel (1:1 EtOAc:hexanes) and concentrated to give the title compound. N2 (g) was bubbled through the solution for 5 minutes CO (g) was bubbled into the reaction mixture for five minutes The reaction was worked up then filtered through a plug of silica gel (1:1 EtOAc:hexanes) concentrated

实验步骤: 1-(3-Bromo-phenylsulfanyl)-propan-2-one (1.5 g, 6.12 mmol) and 3-chlorophenylhydrazine hydrochloride (1.21 g, 6.73 mmol) were combined in t-BuOH (50 mL) and the reaction was heated to 80° C. and stirred overnight. After cooling the reaction was worked-up using standard procedures to afford a crude mixture of two regioisomers which was then purified using silica gel chromatography (0-30% EtOAc in hexanes) to give the title compound. After cooling the reaction to afford a crude mixture of two regioisomers which was then purified

实验步骤: 3-Bromothiophenol (2.89 g, 15.29 mmol) and chloroacetone (1.278 mL, 16.06 mmol) were mixed in THF (80 mL) and cooled to 0° C. N,N-Diisopropylethylamine (6.65 mL, 38.23 mmol) was added and the reaction was stirred at 0° C. for five minutes then allowed to warm to room temperature and stirred overnight. The reaction was then extracted with EtOAc and H2O and the organic portion was concentrated to afford the title compound. to warm to room temperature stirred overnight The reaction was then extracted with EtOAc and H2O the organic portion was concentrated
