Modification of Chiral Monodentate Phosphine Ligands (MOP) for Palladium-Catalyzed Asymmetric Hydrosilylation of Cyclic 1,3-Dienes

Several MOP ligands 5 containing aryl groups at 2′ position of (R)-2-(diphenylphosphino)-1,1′-binaphthyl skeleton were prepared and used for palladium-catalyzed asymmetric hydrosilylation of cyclic 1,3-dienes 6 with trichlorosilane. Highest enantioselectivity was observed in the reaction of 1,3-cyclopentadiene (6a) catalyzed by a palladium complex (0.25 mol %) coordinated with (R)-2-(diphenylphosphino)-2′-(3,5-dimethyl-4-methoxyphenyl)-1,1′- binaphthyl (5f), which gave (S)-3-(trichlorosilyl)cyclopentene of 90% ee.

Asymmetric hydrosilylation of cyclohexa-1,3-diene with trichlorosilane by palladium catalysts coordinated with chiral phosphoramidite ligands

Chiral phosphoramidite ligands prepared from (S)-binaphthol and various secondary amines were examined for the palladium-catalyzed asymmetric hydrosilylation of cyclohexa-1,3-diene with trichlorosilane. With a sterically demanding phosphoramidite bearing bis(diphenylmethyl)amine, the high enantiomeric excess of 87% was achieved, which is the highest enantioselectivity in the hydrosilylation of cyclohexadiene reported to date. The catalytic activity in the present hydrosilylation was high with all of the ligands employed, while the enantioselectivities varied dramatically depending on the dialkylamine moiety of the phosphoramidite ligand.

A new entry to carbocyclic nucleosides: Oxidative coupling reaction of cycloalkenylsilanes with a nucleobase mediated by hypervalent iodine reagent

(Chemical Equation Presented) A novel method for synthesizing carbocyclic nucleosides was developed. The new synthesis includes a direct coupling reaction of cycloalkenylsilanes with a silylated nucleobase catalyzed by a hypervalent iodine reagent. By app

Enhanced catalytic activity in asymmetric hydrosilylation of 1,3-dienes with a soluble palladium catalyst

A new MOP ligand 8 containing two n-octyl groups at the 6 and 6′ positions of the (R)-2-(diphenylphosphino)-2′-aryl-1,1′-binaphthyl skeleton was prepared and used for the palladium-catalyzed asymmetric hydrosilylation of 1,3-dienes with trichlorosilane. T

Preparation of a new MOP ligand containing a long-chain alkyl group and its use for palladium-catalyzed asymmetric hydrosilylation of cyclic 1,3-dienes

A new MOP ligand containing n-octyl group at 6 and 6′ positions of (R)-2-(diphenylphosphino)-2′-aryl-1,1′-binaphthyl skeleton was prepared and used for palladium-catalyzed asymmetric hydrosilylation of cyclic 1,3-dienes with trichlorosilane. By introducti
