Synthetic Route of 127294-73-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.127294-73-9, Name is (R)-Piperidin-3-amine, molecular formula is C5H12N2. In a Patent£¬once mentioned of 127294-73-9
A methof for preparing (R)- (+) – 3 – amino piperidine dihydrochloride method (by machine translation)
The invention discloses a chemical methof for preparing (R)- (+) – 3 – amino piperidine dihydrochloride method, which belongs to the racemic compound split field. Specifically using 1 – 2 equivalent of (+) – 4 – (2 – chlorophenyl) – 2 – hydroxy – 5, 5 – dimethyl – 2 – oxo – 1, 3, 2 – dioxo phosphorus heterocycle hexane for resolving agent, with a racemic 3 – amino piperidine in reaction salt in the membrane, the temperature of the precipitate solid can burn fully separated from the to obtain optically pure (R)- (+) – 3 – amino piperidine dihydrochloride; mother liquor can burn fully from the recovery (S)- (-) – 3 – amino piperidine dihydrochloride, (S)- (-) – 3 – amino piperidine dihydrochloride after disappearing supination cycle use. The invention has simple operation, resolving agent can be recycled, is suitable for industrial production. (by machine translation)
