Rhodium/phosphoramidite-catalyzed asymmetric arylation of aldehydes with arylboronic acids.
Phosphoramidites are effective chiral ligands in the rhodium catalyzed addition of arylboronic acids to aldehydes providing up to 75% enantioselectivity and up to 96% isolated yield.
متن کاملEnantioselective rhodium-catalyzed addition of arylboronic acids to trifluoromethyl ketones.
The catalytic asymmetric 1,2-addition of a series of arylboronic acids to 2,2,2-trifluoroacetophenones is described with high isolated yields (up to 96%) and good enantioselectivities (up to 83% ee) using a rhodium(I)/phosphoramidite catalyst.
متن کاملLewis acid InBr3-catalyzed arylation of diorgano diselenides and ditellurides with arylboronic acids.
A novel Lewis acid InBr3-catalyzed direct cross-coupling reaction of arylboronic acids with diorgano diselenides and ditellurides without any additive has been developed. The reactions generated the corresponding unsymmetrical diorgano monoselenides and monotellurides in good to excellent yields. The method has advantages of broad substrate scope, simple operation, mild reaction conditions and ...
متن کاملChiral amidophosphane-rhodium(i)-catalyzed asymmetric conjugate arylation of acyclic enones with arylboronic acids.
A catalytic asymmetric conjugate arylation of acyclic alpha,beta-unsaturated ketones with arylboronic acids was catalyzed by 3 mol% of chiral amidomonophosphane 1-rhodium(I) in the presence of potassium hydroxide in a mixture of 1,4-dioxane and water at 70 degrees C to afford 1,4-conjugate arylated acyclic ketones with high enantiomeric excess in high chemical yield. Thirteen examples of the re...
متن کاملChromium(II)-catalyzed enantioselective arylation of ketones
The chromium-catalyzed enantioselective addition of carbo halides to carbonyl compounds is an important transformation in organic synthesis. However, the corresponding catalytic enantioselective arylation of ketones has not been reported to date. Herein, we report the first Cr-catalyzed enantioselective addition of aryl halides to both arylaliphatic and aliphatic ketones with high enantioselect...
