A visible light mediated De Mayo reaction between 1,3-diketones and styrenes following a [2+2] cycloaddition pathway via a photosensitization mechanism gives access to 1,5-diketones. The reaction has been applied to substituted styrenes and aryl- and alkyl-substituted ketones. Moreover, the method converts -ketoesters, -amido esters, and -cyano ketones. Seven membered rings, a frequent structural motif of natural products, are also accessible using this methodology.
