乙基1-氟-2-环己酮羧酸酯

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

实验步骤: Referring to the process described in Bulletin des Societe Chimiques Belges volume 87, page 223 (1978), 5.4 g (30 mmol) of ethyl 1-fluoro-2-oxocyclohexanecarboxylate was dissolved in 50 ml of toluene, to this was added 6.0 g (15 mmol) of Lawesson's reagent, and reaction was carried out at 100° C. for 5 hours. 100 ml of hexane was added, the precipitate was filtered out and the solvent was distilled away. The filtrate was purified by silica gel column chromatography (developing solvent: hexane / ethyl acetate=15/1) to obtain 1.1 g (yield: 18 % of ethyl 1-fluoro-2-mercapto-2-cyclohexenecarboxylate. to this was added the precipitate was filtered out the solvent was distilled away The filtrate was purified by silica gel column chromatography (developing solvent: hexane / ethyl acetate=15/1)
