Reactive Ketenes through a Carbonate/Amine Shuttle Deprotonation Strategy: Catalytic, Enantioselective α-Bromination of Acid Chlorides
摘要:
[GRAPHICS]We have developed an efficient methodology for the generation of ketenes by employing a catalytic shuttle base and potassium carbonate as a stoichiometric base, We have applied this technology to the catalytic, asymmetric a bromination of acid chlorides.
