Application
- Nickel-catalyzed asymmetric α-arylation and heteroarylation of ketones with chloroarenes
- Enantioselective synthesis of dihydrobenzofurans and dihydronaphthofurans via olefin isomerization/enantioselective intramolecular Alder-ene reaction of enynes catalyzed by Rh
- Preparation of axially chiral biaryl compounds by gold-catalyzed stereoselective intramolecular hydroarylation
- Preparation of chiral silylated homoallylic alcohols and diols by asymmetric addition of alcohols and aldehydes to silylbutadienes catalyzed by ruthenium complexes
- Preparation of chiral 3-alkyl-substituted indolines by tandem condensation-asymmetric hydrogenation of indoles with aldehydes, catalyzed by Bronsted acids and palladium BINAP complexes
- Rhodium-catalyzed asymmetric formal olefination or cycloaddition of 1,3-dicarbonyl compounds with 1,6-diynes or 1,6-enynes
