Abstract

The new potentially best-in-class β-lactamase inhibitor IID572 was discovered by a late stage functionalization approach. An alternative scalable synthesis was developed to satisfy the short-term need for tox studies. The two key features were an intramolecular azomethine ylide [2+3] cycloaddition that allowed the quick formation of molecular complexity from cheap starting material and an efficient enzymatic resolution that resulted in high optical purity of a key intermediate.
