To establish an efficient, high-yield synthetic procedure for preparing 7-aminocephalosporanic acid and its esters from cephalosporin C derivatives.
Conducted intramolecular aminolysis on ester derivatives of the antibiotic cephalosporin C.
Synthesized and converted imino-ether intermediates derived from cephalosporin C esters into 7-aminocephalosporanic acid.
Demonstrated the successful cleavage of cephalosporin C side chains through both intramolecular aminolysis and imino-ether routes.
Achieved a simplified, high-yield chemical procedure for isolating pure 7-aminocephalosporanic acid.
