Abstract
AbstractThe increase and spread of Gram‐negative bacteria that resistant are to almost all currently available β‐lactam antibiotics is a major global health problem. The primary cause for drug resistance is the acquisition of metallo‐β‐lactamases such as metallo‐β‐lactamase‐1 (NDM‐1). The fungal natural product aspergillomarasmine A (AMA), a fungal natural product, is an inhibitor of NDM‐1 and has shown promising in vivo therapeutic potential in a mouse model infected with NDM‐1‐expressing Gram‐negative bacteria. The first total synthesis and stereochemical configuration reassignment of aspergillomarasmine A is reported. The synthesis highlights a flexible route and an effective strategy to achieve the required oxidation state at a late stage. This modular route is amenable to the efficient preparation of analogues for the development of metallo‐β‐lactamase inhibitors to potentiate β‐lactam antibiotics.
