Stereoselective Ferrier-Type O-Glycosylation Enabled by Difluoromethylated Glycal Donors. [PDF]
Adv Sci (Weinh)A fluorine‐mediated stereoselective Ferrier‐type glycosylation is reported. Glycals are pre‐decorated with photo‐2‐difluoroalkylation and reacted with diverse acceptors to obtain exclusively α‐selective Ferrier rearrangement products. Abstract The effective construction of structurally homogeneous glycosides is requisite in oligosaccharide assembly and

Intermolecular Enantioselective Nickel‐Catalyzed Arylation of Un‐Activated C(sp3)─H Bond
Angewandte Chemie International Edition, EarlyView.Ni: a new solution for asymmetric C(sp3)─H activation. The stereoselective synthesis of all‐carbon quaternary stereogenic centres is achieved via enantioselective C(sp3)─H arylation using a Ni‐BINOL‐derived catalyst. Rational catalytic cycle design uncovers a new reaction pathway that can efficiently induce chiral information during the stereoselective
