A highlyenantioselectiverhodium catalysed asymmetric arylation (RCAA) of nitroolefins with arylboronicacids is presented using a newly developed, C1-symmetric, non-covalent interacted, phellandrene derived, nordehydroabietyl amide-containing chiral diene under mild conditions. Stereoelectronic effects were studied, suggesting an activation of the bound substrate through the secondary amide as a

Multifunctional isoquinoline-oxazolines (MIQOXs) were conceived and synthesized from commercially available chiral amino acids. The multifunctional role of MIQOXs was demonstrated by Pd-catalyzed highly enantioselective addition of arylboronic acids to nitrostyrenes, and by the discovery of novel antifungal candidates.

A palladium-catalyzedasymmetricaddition of arylboronicacids to nitrostyrene is reported. The catalytic system employing iPr-IsoQuinox as a chiral ligand in MeOH solvent under an air atmosphere provides the chiral diarylsubstituted products in high yields with good enantioselectivities. A variety of functionalized nitrostyrenes can be used, and the method tolerates some variation in arylboronic acid

An efficient rhodium‐catalyzed enantioselective addition of potassium organotrifluoroborates to nitroalkenes powered by simple chiral sulfur‐olefin ligands is reported. This protocol is applicable to a broad range of 2‐aryl‐, alkyl‐, and heteroaryl‐substituted nitroalkenes, allowing access to diverse chiral β,β‐disubstituted nitroethanes in good to excellent yields with high enantioselectivity under
