Visible Light-Induced Aerobic Epoxidation of α,β-Unsaturated Ketones Mediated by Amidines

An aerobic photoepoxidation of α,β-unsaturated ketones driven by visible light in the presence of tetramethylguanidine (3b), tetraphenylporphine (H2TPP), and molecular oxygen under mild conditions was revealed. The corresponding α,β-epoxy ketones were obtained in yields of up to 94% in 96 h. The reaction time was shortened to 4.6 h by flow synthesis. The mechanism related to singlet oxygen was supported by experiments and density functional theory (DFT) calculations.

One-Pot Aerobic Photooxidative Darzens Reaction from Styrene and Benzyl Alcohol via Phenacyl Iodide and Benzaldehyde by Using?- Iodine

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.

Visible-Light-Promoted Photoredox Syntheses of α,β-Epoxy Ketones from Styrenes and Benzaldehydes under Alkaline Conditions

A range of styrenes and benzaldehydes were smoothly combined to form α,β-epoxy ketones under the synergistic actions of photocatalyst Ru(bpy)3Cl2, tert-butyl hydroperoxide (t-BuOOH), cesium carbonate (Cs2CO3), and visible light irradiation. The process likely proceeds through visible-light-enabled photocatalytic generations of acyl radicals as key intermediates.
