Gourdet, Benoit published the artcileRhodium-catalyzed carbometalation of ynamides with organoboron reagents, Quality Control of 480438-56-0, the main research area is oxazolidinone alkynyl rhodium catalyst carbometalation; ynamide carbometalation stereoselective regioselective rhodium catalyst; enamide stereoselective regioselective preparation.
In the presence of catalytic [Rh(cod)(MeCN)2]BF4, ynamides undergo carbometalation with boronic acids, arylboronic esters, and triarylboroxines. These reactions enable the regio- and stereocontrolled synthesis of multisubstituted enamides. E.g., reaction of 3-(2-phenylethynyl)oxazolidin-2-one with 4-chlorophenylboronic acid gave 65% 3-[(E)-2-(4-chlorophenyl)-2-phenylvinyl]oxazolidin-2-one (I).
Tetrahedron published new progress about Addition reaction catalysts, regioselective. 480438-56-0 belongs to class chlorides-buliding-blocks, name is 3-Chloro-4-isopropoxyphenylboronic acid, and the molecular formula is C9H12BClO3, Quality Control of 480438-56-0.
