Abstract: A coupling of acrylic acids/benzoic acids with α-diazocarbonyl compounds has been realized by a combined catalytic system of rhodium catalyst and Zn(OAc)2 additive. The presence of Zn(OAc)2 obviously accelerates the C(sp2)-H activation and destructed the…

Abstract: A CuH-catalyzed coupling of aryl alkenes with 3-aryl-2H-azirines has been developed to synthesize optically active β,β-disubstituted ketones. We propose that this protocol occurs through a sequence in which a chiral alkylcopper complex regioselectively attacks the…

Abstract: In the literature, C–N coupling methods for the reaction of iodo-oxazole with 2-pyridinone were found to be low yielding. C–N coupling using silver benzoate additives with CuI catalysts and 4,7-dimethoxy-1,10-phenanthroline ligands has been developed to…

Abstract: A neighboring boronate group in the substrate provides a dramatic rate acceleration in transmetalation to copper and thereby enables organoboronic esters to participate in unprecedented site-selective cross-couplings. This cross-coupling operates under practical experimental conditions and…

Abstract: A novel and efficient protocol for the synthesis of various 2,4-disubstituted, 1,2,4-trisubstituted and 1,2,4,5-tetra-substituted imidazoles via cascade palladium catalyzed C-C coupling followed by intramolecular C-N bond formation was developed. Readily accessible boronic acids and N-substituted-2-aminoacetonitriles…
