Catalytic enantioselective defluorinative functionalization of easily accessible allylic fluorines is well recognized as one the most attractive strategies for creating stereogenic centers with high enantioselectivity. This highlight review precisely aims to summarize recent developments this area mainly from following six aspects: defluoroarylation, defluoroalkylation, defluoroborylation, defl...

Highly enantiomerically enriched (h-arene)tricarbonylchromium(0) complexes whose chirality originates from the 1,2disubstitution pattern of the arene and the coordination of the metal to one enantiotopic face of the arene are powerful chirons in asymmetric synthesis. Robust, planar chiral arene complexes also increasingly find application as chiral ligands in asymmetric catalysis. Enantiomerica...

Atropisomeric molecules are a privileged class of stereogenic material that have important applications in catalysis, materials science and medicines. To date, the majority work has been focused upon biaryl heterobiaryl scaffolds involving restricted rotation between pair cyclic fragments, but C–N atropisomeric based amines amides where nitrogen atom is not part ring system rapidly emerging as ...
