Recent advances in the synthesis of 1,3-diketones

The most recent achievements in the construction of the 1,3-diketone moiety are reviewed. Though both classical and modern approaches to the synthesis of 1,3-diketones are compared and analyzed in terms of efficiency, functional group compatibility, regio-, and stereoselectivity, main attention is paid to recently discovered methods based on rearrangements and concerted mechanisms. Molecular structure investigations, appearance in nature, and biological activity of 1,3-diketones are also briefly reviewed.
