Description and Uses

Catalytic ligand used for:

• 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 3-alkyl-substituted indolines by tandem condensation-asymmetric hydrogenation of indoles with aldehydes, catalyzed by Bronsted acids and palladium BINAP complexes
• Stereoselective preparation of hydrindanes and decalins containing up to four contiguous stereocenters via rhodium-catalyzed [2+2+2] cycloaddition of ene-allenes with allenes
• Rhodium-catalyzed asymmetric formal olefination or cycloaddition of 1,3-dicarbonyl compounds with 1,6-diynes or 1,6-enynes
• Stereoselective preparation of 2,3-substituted indolines via Pd-catalyzed hydrogenation of (α-hydroxyalkyl)indoles
