The reaction of nocardicin A in acid: concurrent hydrolysis of an oxime and a β-lactam
Abstract
The mechanism of acid hydrolysis of the microbial antibiotic nocardicin A has been examined by a comparison of its kinetic dependence upon acid concentration with those of several β-lactams and oximes. It is concluded that, in moderately concentrated sulphuric acid, the faster reaction is β-lactam hydrolysis but that the spectral changes are due to hydrolysis of the oxime group.
