Structure elucidation of MM 17880, a new fused β-lactam antibiotic isolated from Streptomyces olivaceus; a mild β-lactam degradation reaction

Abstract
The structure of the olivanic acid derivative (1) has been confirmed by a novel β-lactam degradation in dimethyl sulphoxide; application of this reaction has resulted in the structure elucidation of a new antibiotic, MM 17880.
