Two-step methodology described herein showcases the first example of an oxidation/oxidative amidation cyclization cascade of MCR products toward diverse N-functionalized isatins. Products of both the Ugi 3CR and the Ugi azide reactions are oxidatively cyclized through a postcondensation process utilizing selenium dioxide. This methodology was found to be applicable for the generation of bis-peptidomimetic-like isatins containing multiple points of diversification.
