Iridium-catalyzed chemoselective transfer hydrogenation of α, β-unsaturated ketones to saturated ketones in water
A chemoselective iridium-catalyzed transfer hydrogenation of α, β-unsaturated ketones was realized in water. The C[dbnd]C double bonds of 2-benzylidene indanones and analogues were hydrogenated exclusively catalyzed by an iridium complex (0.1 mol%) bearin
Enantioselective α-Carbonylative Arylation for Facile Construction of Chiral Spirocyclic β,β′-Diketones
We herein describe the first enantioselective α-carbonylative arylation, providing a diverse set of chiral spiro β,β′-diketones bearing various ring sizes and functionalities in high yields and good to excellent enantioselectivities. Calculations suggest the transformation proceeds through reductive elimination instead of nucleophilic addition pathway.

Michael addition of malononitrile to indenones: Synthesis and characterization of 2-(1-oxo-2,3-dihydro-1H-inden-2-yl) (aryl)(methyl)malononitrile derivatives
Indanones 3 were prepared from the reaction of indanone (1) with corresponding benzaldehyde derivatives 2, as described in the literature. Then, indenones 3 were subjected to KOtBu-catalyzed Michael addition with malononitrile to give a mixture of diaster

Free radical-mediated chemoselective reduction of enones
A novel methodology has been devised for the chemoselective reduction of enones involving the use of nBu3SnH and azobisisobutyronitrile. The 1,4-reduction of variously substituted ,β-unsaturated cyclic and acyclic enones has been successfully c
