Highly chemo- and regioselective rearrangement of α,β-epoxy ketones to 1,3-dicarbonyl compounds in 5 mol dm–3 lithium perchlorate–diethyl ether medium
Abstract
Epoxides from α,β-unsaturated ketones undergo highly chemo- and regioselective rearrangement to 1,3-dicarbonyl compounds in 5 mol dm–3 lithium perchlorate–diethyl ether medium by a 1,2-migration of the carbonyl group at ambient conditions.
