Transformation of 7-(4-Hydroxyphenylacetamido)cephalosporanic Acid into a New Cephalosporin Antibiotic, 7-[1-Oxaspiro(2.5)octa-6-oxo-4, 7-diene-2-carboxamido]ceph-alosporanic Acid, by Laccase

7-(4-Hydroxyphenylacetamido)cephalosporanic acid (1) was transformed into 7-[1-oxaspiro(2.5)octa-6-oxo-4, 7-diene-2-carbox-amido]cephalosporanic acid (2) by laccase-catalyzed phenolic oxidation. 2 consisted of two diastereomers, named CXL-1 and CXL-2. CXL-2 was 10-30 times more active than CXL-1, al...
