One out of Four: Kinetic Resolution of Stereoisomeric Mixtures of Secondary Alcohols with a Quaternary Carbon Atom in the β-Position by Cu-H-Catalyzed Enantioselective Silylation
{{output}}
An enantio- and diastereoselective Cu-H-catalyzed silylation of acyclic secondary alcohols with a vicinal quaternary stereocenter is reported. The reaction kinetically selects one out of four stereoisomers, affording the fastest-reacting stereoisomer as the si... ...
