Radical Process

A nitrogen-centered radical-mediated strategy is described to synthesize functionalized 3-acylcoumarins. This process is enabled by visible-light-induced acylation/cyclization reactions of alkynoates with various acyl oxime compounds in acetonitrile. The difunctionalization of...

An unprecedented visible-light inspired selective radical azidation of unactivated and diverse substituted vinylarenes with sulfonium iodate reagent has been realized. The intrinsic radical process triggered by light tolerated several synthetically useful functionalities enabling two new carbon-hetero bonds which display distinctive late-stage applications to biologically relevant scaffolds.

A three-component radical process is reported that, by coupling alkyl chlorides, maleimides, and heteroaromatic fragments, installs multiple biologically relevant heterocycles within complex cascade products. This method, which generates radicals via an SN2-based photochemical catalytic mechanism, activates substrates incompatible with or inert to classical radical-generating strategies.
