A method for the synthesis of cyclic 3-aryl- and heteroaryl-substituted 1,2-dicarbonyl compounds with different ring sizes by using a Suzuki cross-coupling reaction between 3-halo-1,2-dicarbonyl compounds and arylboronic acids is developed. The 3-halo-1,2-dicarbonyl substrates are easily available from 1,2-dicarbonyl compounds. The method is versatile, affording good to high yields of the target compounds.

By using an iron-based catalyst, access to enantioenriched 1,1-diarylakanes was enabled through an enantioselective Suzuki-Miyaura crosscoupling reaction. The combination of a chiral cyanobis(oxazoline) ligand framework and 1,3,5-trimethoxybenzene additive were essential to afford high yields and enantioselectivities in cross-coupling reactions between unactivated aryl boronic esters and a variety of benzylic chlorides, including challenging ortho-substituted benzylic chloride substrates. Mechanistic investigations implicate a stereoconvergent pathway involving carbon-centered radical intermediates.
