Catalytic multicomponent [m + n + o]-type cycloadditions offer efficient, atom-economical routes to diverse complex carbocycles. Recently, such transformations have emerged as unique strategies for medium ring carbocycle synthesis. Despite the important developments in this area, however, highly enantioselective [m + n + o]-type processes accessing medium ring carbocycles have yet to be developed. Herein, a rhodium-catalyzed [4 + 2 + 2] cycloaddition of allenedienes with allenes enabling the direct stereoselective synthesis of cis-fused cyclooctanoids is reported. These cycloadditions are successful with a diverse range of -components and demonstrate the potential for high levels of enantioselectivity in a [4 + 2 + 2] process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of N,N-Dimethyldinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, you can also check out more blogs about345967-22-8

Copper(I) has become the preferred metal to catalyze the beta-boration of alpha,beta-unsaturated carbonyl compounds, and now we demonstrate that easily accessible monodentate chiral ligands, such as phosphoramidites and phosphites, can be convenient alternative ligands to induce asymmetry in the enantioselective version of this reaction, particularly in the beta-boration of alpha,beta-unsaturated imines.

Access to Spiroindolines and Spirodihydrobenzofurans via Pd-Catalyzed Domino Heck Spiroyclization through C-H Activation and Carbene Insertion

A new palladium-catalyzed domino approach for the synthesis of attractive spirocyclic indolines and dihydrobenzofurans was developed. The reaction proceeds through a sequential intramolecular Heck spirocyclization, remote C-H activation, and diazocarbonyl carbene insertion. Various spiroindolines and spirodihydrobenzofurans containing two quartenary carbon stereocenters were readily obtained in good to excellent yields. A preliminary study of asymmetric spirocyclization using chiral monophosphoramidite as a ligand was also conducted, enabling access to highly valuable chiral spiroindolines with up to 80% ee.
