Iron-Catalyzed Carbonylation-Peroxidation of Alkenes with Aldehydes and Hydroperoxides
摘要:
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.

Lithium t-butyl hydroperoxide (easily generated by addition of an alkyl-lithium to anhydrous t-butyl hydroperoxide in THF solution) is a powerful reagent for the epoxidation of electrophilic alkenes at –20 to 0 °C under full stereocontrol.
