Use | 2-tetrahydrofuran carboxylic acid (tetrahydrofuran-2-carboxylic acid, 2-THFA), respectively, after resolution (R)-2-THFA and (S)-2-THFA, chiral 2-tetrahydrofurancarboxylic acid are important ligand synthons in asymmetric synthesis reactions. (R)-2-THFA is an important intermediate for the synthesis of the antibiotic furopenem, which can be used as an antagonist of antigen VLA-4, and is also an important intermediate of the super influenza drug Xofluza. 2-THFA is the main raw material for the preparation of chiral auxiliary (S)-acetyl Tetrahydrofuran, is the raw material for the preparation of cephalosporin antibiotic intermediates, and is also an important intermediate for the preparation of hormone releasing hormone LHRH. pharmaceutical synthesis intermediates. for pharmaceutical intermediates |
