Abstract

We report a one-pot protocol for the synthesis of α,β-epoxy ketones from benzyl alcohols and styrenes with molecular oxygen, visible light, and molecular iodine. This procedure involves simultaneous aerobic photooxidative transformation of a benzyl alcohol into a benzaldehyde and of a styrene into a phenacyl iodide, with a subsequent Darzens reaction in one pot. This is the first report of a one-pot oxidative Darzens reaction starting from benzyl alcohols and styrenes.
