Ruthenium-Catalyzed Aldehyde Functionality Reshuffle: Selective Synthesis of E-2-Arylcinnamaldehydes from E-β-Bromostyrenes and Aryl Aldehydes
摘要:
A new concept for highly selective synthesis of E-2-arylcinnamaldehydes has been developed via a formal arylformylation of E-beta-bromostyrenes with readily available aryl aldehydes. This strategy involves an overall reshuffle of the aldehyde functionality with a loss of hydrogen bromide.
