Abstract
Aromatic hydrocarbons are some of the most elementary feedstock chemicals, produced annually on a million metric ton scale, and are used in the production of polymers, paints, agrochemicals and pharmaceuticals. Dearomatization reactions convert simple, readily available arenes into more complex molecules with broader potential utility, however, despite substantial progress and achievements in this field, there are relatively few methods for the dearomatization of simple arenes that also selectively introduce functionality. Here we describe a new dearomatization process that involves visible-light activation of small heteroatom-containing organic molecules—arenophiles—that results in their para-cycloaddition with a variety of aromatic compounds. The approach uses N–N-arenophiles to enable dearomative dihydroxylation and diaminodihydroxylation of simple arenes. This strategy provides direct and selective access to highly functionalized cyclohexenes and cyclohexadienes and is orthogonal to existing chemical and biological dearomatization processes. Finally, we demonstrate the synthetic utility of this strategy with the concise synthesis of several biologically active compounds and natural products.

In the version of this Article originally published, in the Figure 2 caption, the HOMO–LUMO gap of the arene, rather than the arenophile, was described as the first requirement for arenophile reactivity. Furthermore, in the caption for Table 3, an oversight resulted in the inclusion of p-TsNH2 as the additive, however, the additive used in this reaction was citric acid (0.5 equiv.); and 2.0 equivalents of NMO were used. This has been corrected in the online versions of this Article.
