Analyzing the synthesis route of 673-06-3

With the synthetic route has been constantly updated, we look forward to future research findings about D-Phenylalanine,belong chiral-catalyst compound

As a common heterocyclic compound, it belong chiral-catalyst compound,D-Phenylalanine,673-06-3,Molecular formula: C9H11NO2,mainly used in chemical industry, its synthesis route is as follows.,673-06-3

(R)-phenylalanine (4.2 g, 25 mmol) was sequentially added to the dry reaction flask.Water (30mL),1,4-dioxane(30mL) andSodium bicarbonate (5.1 g, 61 mmol),After the mixture was stirred for 10 minutes,Add (Boc) 2O (10.1g,45.8mmol),The resulting mixture was stirred at room temperature for 24 h.After the reaction, the solvent was distilled off under reduced pressure, the resulting residue was washed with water (20mL) and EtOAc (100mL) was diluted with 1M HCl and then adjusted to pH 6-7, was allowed to stand, and the organic layer was washed with water and saturated brine, dried over anhydrous sulfate Dry the sodium, filter, and distill off the solvent under reduced pressure.The title compound was obtained as a colorless oil (6.0 g, 91%)

With the synthetic route has been constantly updated, we look forward to future research findings about D-Phenylalanine,belong chiral-catalyst compound
