Ni-catalyzed reductive antiarylative cyclization of alkynones

A new catalyst system for the antiarylative cyclization of alkynones and aryl halides through a reductive cross-coupling strategy is developed. The transformation proceeds smoothly in the absence of organometallic reagents and features high functional group tolerance. This method provides an effective platform to access a wide variety of synthetically useful endocyclic tetrasubstituted allylic alcohols in a stereoselective manner.

Enantioselective Copper-Catalyzed Desymmetrization of 1,3-Diketones Involving Borylation of Styrenes

A copper-catalyzed intramolecular enantioselective and diastereoselective borylative coupling of styrenes and ketones was achieved by merging desymmetrization strategy and olefin difunctionalization. The reaction proceeds through an initial enantioselective borylcupration of styrenes, followed by a highly selective direct addition to 1,3-diketones. The bicyclic scaffolds with three chiral carbon centers, including two tetrasubstituted carbons, were generated in excellent yields, diastereoselectivities, and enantioselectivities. This catalytic tandem reaction has great potential for further synthetic application of the chiral polycyclic compounds, because of the versatility of the functional groups in the products.
