(R)-2-Amino-3-(4-hydroxy-phenyl)-propionicacidtert-butylester - Introduction
tert-butyl D-tyrosinate is a chiral compound and is the tert-butyl ester derivative of D-tyrosine. Its chemical formula is C15H23NO4.
Nature:
tert-butyl D-tyrosinate is a colorless liquid with a special smell. It has good solubility and good solubility in organic solvents.
Use:
tert-butyl D-tyrosinate can be used as reagents and catalysts for organic synthesis reactions. It has a wide range of applications in the synthesis of drugs, dyes, fragrances and functional compounds.
Preparation Method:
tert-butyl D-tyrosinate can be prepared by reacting D-tyrosine with tert-butanol. The reaction is generally carried out under an inert atmosphere, typically with an acid catalyst such as sulfuric acid, formic acid or acetic acid.
Safety Information:
tert-butyl D-tyrosinate are generally safe under correct operation, but laboratory safety practices still need to be followed. It may be irritating to the eyes, skin and respiratory tract, so wear appropriate protective measures such as gloves, goggles and a protective mask when used. In addition, it should be kept away from fire and oxidizing agents, and stored in a sealed container to avoid exposure to air. If exposed or inhaled, wash the affected area immediately and seek medical help.
