General description

(+)-6-Aminopenicillanic acid is the core moiety of different penicillins. It can be prepared from the benzylpenicillin silyl ester via cleavage of the amide bond. The coating of (+)-6-aminopenicillanic acid on silver nanoparticles (6APA-AgNPs), imparts them with an ability to detect chromium (IV) in human erythrocytes.
Chemical structure: ß-lactam

Application

(+)-6-Aminopenicillanic acid can be used as a starting material for the synthesis of (6S,7S)-cephalosporins, and organotin polyamine esters by reacting with organotin dihalides via interfacial polycondensation.
It reacts with higher amino acid Schiff bases to form the corresponding β-lactam derivatives.4
