• Beschreibung

  L-Serine benzyl ester hydrochloride, also known as L-Serine-Bz-HCl, is a derivative of the amino acid L-Serine. It is a water-soluble, white crystalline powder and is commonly used as a reagent in biochemical and physiological studies. It is a useful raw material that could synthesize mang organic compounds, such as a cyclic sulfamidate which could reacted cleanly with the sodium thiolate salt of a variety of unprotected 1-thio sugars in aqueous buffer to afford the corresponding S-linked amino acid glycoconjugates in good yields after hydrolysis of the N-sulfates[1].

• synthetische

  Boc-L-Ser-OBz (2.953 g, 10 mmol) was dissolved in MeOH (21 mL) and was palced in ice bath. Then concentrated hydrochloric acid (4.25 mL) was added dropwise. The ice bath was removed and the reaction mixture was stirred for 3 hours. After that the isopropanol (10 mL) was added and the volatile components were removed under reduced pressure at 55 ℃. The oily residue was coevaporated with isopropanol three times (3x10 mL). L-Serine benzyl ester hydrochloride ( yield=69%) was crystallized from H2O/iPr-OH/acetone mixture.
