Abstract
Herein, we report the structure and synthesis of the potent MDM2-p53 inhibitor BI-0282. The complex spirooxindole scaffold bearing four stereocenters embedded in a rigid polycyclic ring-system was effectively prepared on a multi-gram scale in only five synthesis steps employing a three-component 1,3-dipolar cycloaddition and a late-stage Davis–Beirut reaction as key steps.
