The first catalytic asymmetric conjugate addition to γ,δ-unsaturated β-dicarbonyl compounds was developed. With a chiral diene-rhodium(I) μ-chloro dimer as the catalyst in toluene/H2O, asymmetric conjugate arylation of γ,δ-unsaturated β-dicarbonyl compounds with arylboronic acids proceeded in high efficiency with excellent enantioselectivities. The generated β-dicarbonyl products are versatile chiral synthons, which can be easily converted to diverse important chiral structures.
Chemoselective aromatic C-H insertion of α-diazo-β-ketoesters catalyzed by dirhodium(II) carboxylates

supporting information; experimental part, p. 238 - 240 (2012/03/11)
The ability of α-diazo-β-ketoesters bearing a substituent on the benzylic position to undergo aromatic C-H insertion is described. Good to excellent yields of the aromatic C-H insertion products were observed with Rh2(tpa)4 or Rhsub
