Lee, Minhan published the artcileModular Tuning of Electrophilic Reactivity of Iridium Nitrenoids for the Intermolecular Selective α-Amidation of β-Keto Esters, Category: esters-buliding-blocks, the main research area is dicarbonyl compound trichloroethoxycarbonyl azide iridium catalyst chemoselective amidation; amido dicarbonyl compound preparation.
Ir-catalyzed intermol. amino group transfer to β-keto esters (amides) to α-aminocarbonyl products with excellent chemoselectivity was reported. The key strategy was engineered electrophilicity of the putative Ir-nitrenoids by tuning electronic property of the κ2-N,O chelating ligands, thus facilitated nucleophilic addition of enol π-bonds of 1,3-dicarbonyl substrates.
Journal of the American Chemical Society published new progress about Amidation (chemoselective). 140-11-4 belongs to class esters-buliding-blocks, name is Benzyl acetate, and the molecular formula is C9H10O2, Category: esters-buliding-blocks.
