2-(4-ethoxycarbonylcyclohexylidene)acetic acid

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

实验步骤: To a solution of 2-(4-(ethoxycarbonyl)cyclohexylidene)acetic acid (6.0 g, 28.3 mmol) in EtOH (50 ml) was slowly added 10% Pd/C (306 mg). The solution was hydrogenated overnight. The catalyst was filtered off. The filtrate was concentrated in vacuo to afford 2.5 g of product as colorless oil (42%). The catalyst was filtered off The filtrate was concentrated in vacuo

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

实验步骤: To a solution of ethyl 4-(2-tert-butoxy-2-oxoethylidene)cyclohexanecarboxylate (5.3 g, 21 mmol) in CH2Cl2 (30 ml) was added TFA (30 ml). The solution was stirred at room temperature overnight. The solution was concentrated in vacuo to afford 6 g of product as colorless oil, which was used directly for next step without further purification. The solution was concentrated in vacuo
