Shibata, Takanori; Kurita, Hisaki; Onoda, Sahoko; Kanyiva, Kyalo Stephen published the artcile< Ir-Catalyzed Enantioselective Intra- and Intermolecular Formal C-H Conjugate Addition to å°?Substituted ä¼?å°?Unsaturated Esters>, Category: esters-buliding-blocks, the main research area is amidophenyl methylfumarate preparation iridium catalyst enantioselective conjugate addition; amido dihydrobenzofuran acetate preparation; phenyl benzamide methyl alkenoate iridium catalyst enantioselective conjugate addition; methyl benzamido phenylalkanoate regioselective chemoselective preparation.
An enantioselective intramol. formal C-H conjugate addition of 4-Me 1-aryl 2-methylfumarates proceeded using a chiral iridium catalyst. A benzoylamide group served as a directing group and chiral �lactones with a quaternary all-carbon stereogenic center were obtained with up to excellent ee. In the intermol. reaction of N-arylbenzamides with �substituted acrylates, C-H bond activation selectively occurred at the ortho-position of carbonyl groups and highly enantioselective formal C-H conjugate addition proceeded.
Asian Journal of Organic Chemistry published new progress about Addition reaction catalysts, stereoselective (regioselective). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Category: esters-buliding-blocks.
