(R)-(-)-2-Amino-1-propanol Use and Manufacturing

Methods of Manufacturing

The present embodiment relates to a class of long-chain ethyl piperazine sulfonamide derivative intermediate () in the general synthetic methods.Particularly to the synthesis of L- propylamine alcohol.The 150mL dry THF and 1.1gLiAlH(R)-Alanine (10.0 g, 112 mmol) was added solwly to a mixture of lithium aluminium hydride (8.50 g, 224 mmol) in dry THF (300ml) at 0. The mixture was refluxed for 6h, water (8.50 ml) was added slowly, stirred for 15min. Then 15percent NaOH aqueous solution(8.5 ml) was added to the mixture. The crude product was purified by vacuum distillation (Bp: 54 (700Pa)) to give (R)-Alaniol(6.15 g) as a colorless liquid in yield of 73percent.A solution of E1 (19.0 g, 184.5 mmol) in THF (300 ml_) was cooled to 0 °C, and LiAIHExample 26. Separation of rac.-1, 2-propanediol using a chiral selector generated from (4R, 5R)-bis(hydroxydiphenylmethyl)-2, 2-dimethyl-1, 3-dioxolane and Ti(O-isopropyl)

Uses

Used in organic synthesis, used as emulsifier

(R)-(-)-2-Amino-1-propanol has been used as a derivatizing agent for gossypol during the analysis of gossypol enantiomers in cottonseed by high-performance liquid chromatography.
