Synthesis of tyrosine derived diphenol monomers |
摘要 |
A method for preparing diphenol compounds, which method includes the steps of coupling a hydroxyphenyl carboxylic acid with a L-tyrosine ester in a water-miscible organic reaction solvent containing a carbodiimide capable of forming a water-solvent urea by-product, thereby forming a diphenol reaction product; and combining the reaction mixture with an amount of water effective to precipitate the diphenol as a water-immiscible organic phase, so that a water-immiscible organic phase is formed containing the diphenol reaction product. New diphenol monomers and polymers polymerized therefrom are also disclosed.
