A concise and efficient way to synthesize polyenic diones directly from α,β-unsaturated methyl ketones

A concise and efficient approach to polyenic compounds containing important diketone structural fragments is developed from readily available α,β-unsaturated methyl ketones in the presence of copper(II) oxide, iodine, and dimethyl sulfoxide. This is a new carbon-carbon double bond-forming reaction from two methyl sp3 C-H bonds and an attractive route to introduce the SMe group into the molecule from inexpensive dimethyl sulfoxide. The hypothetic self-sorting tandem reaction mechanism is also proposed in this paper.

An efficient method for the selective iodination of ?±,?2- unsaturated ketones

An efficient approach to ?±,?2-unsaturated ?±'-iodo ketones directly from ?±,?2-unsaturated ketones by selective iodination at the ?±'-position, without effect on the double bond and the activated benzene ring, in the presence of copper (II) oxide/iodine is described. The present method has the advantages of high yields, short reaction times, inexpensive reagents, mild reaction conditions, ease of manipulation, and the formation of cleaner products. ?
