乙基 1-苄基-3-羟基哌啶-4-羧酸乙酯

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

实验步骤: Ethyl 1-benzyl-3-hydroxy-4-piperidinecarboxylate in ethanol (10 mL) was treated with Pd(OH)2 (20% on carbon, 50 mg) under a hydrogen atmosphere (1 atm) and stirred for 5 hours. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The reaction mixture was filtered the filtrate was concentrated under reduced pressure

反应条件: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Ethyl 1-benzyl-3-oxo-4-piperidinecarboxylate (1.0 g, 3.8 mmol) in diethyl ether (50 mL) was treated with lithium aluminumhydride (150 mg, 3.9 mmol) at and −78° C. After stirring at −78° C. for 30 minutes, the mixture was allowed to warm to room temperature over 2 hours. The mixture was quenched with saturated ammonium chloride. Standard work-up gave a crude product which was purified via chromatography (SiO2, ethyl acetate:hexanes, 1:6) to provide the title compound. MS (EI, M+H)+ 264. to warm to room temperature over 2 hours The mixture was quenched with saturated ammonium chloride Standard work-up gave a crude product which was purified via chromatography (SiO2, ethyl acetate:hexanes, 1:6)
