1,3-Dimethyl-2-phenylbenzimidazoline (DMPBI)-Acetic Acid: An Effective Reagent System for Photoinduced Reductive Transformation of α,β-Epoxy Ketones to β-Hydroxy Ketones
aqueous solvents. When THF solutions containing aryl carbonyl possessing α,β-epoxyketones and DMPBI and acetic acid were irradiated (λ > 280 nm), β-hydroxy ketones were isolated in good to excellent yields. Photosensitized conditions (λ > 340 nm) were employed for the reactions of alkyl carbonyl possessing α,β-epoxyketones.

A three-component reaction of alkenes, aldehydes, and hydroperoxides catalyzed by FeCl2 to beta-peroxy ketones has been achieved. This three-component reaction can be also applied to the synthesis of a-carbonyl epoxides, through either a stepwise base-induced epoxidation of the separated beta-peroxy ketone products or a one-pot process by simply adding base to the reaction mixture after the completion of the three-component reaction.
