苄基 (3S)-3-(氨基甲基)-3,4-二氢-1H-异喹啉-2-羧酸乙酯

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

实验步骤: To a solution of 20.9 g (64.5 mmol) of the azido compound obtained in Step B in 650 mL of THF, there are successively added 25.5 g (97.2 mmol) of triphenylphosphine and 157 mL of water. The batch is refluxed for 2 hours 30 minutes. The reaction mixture is then concentrated to dryness and the residue oil is then taken up in isopropyl ether. A white precipitate appears; it is filtered off and washed with isopropyl ether. The filtrate is then concentrated to dryness and then purified by chromatography over silica gel using dichloromethane and methanol as eluants. The title product is obtained in the form of an oil. The batch is refluxed for 2 hours 30 minutes The reaction mixture is then concentrated to dryness it is filtered off washed with isopropyl ether The filtrate is then concentrated to dryness purified by chromatography over silica gel
