Pd-catalyzed Arylation of 1,2-Amino Alcohol Derivatives via beta-Carbon Elimination

Herein, we describe a Pd-catalyzed arylation of 1,2-amino alcohols with aryl halides enabled by a retroallylation manifold. This protocol constitutes a new entry point to β-arylated aldehydes via the intermediacy of in situ generated enamine intermediates. The protocol is characterized by its exquisite regioselectivity profile and broad substrate scope – including challenging substrate combinations – even in an enantioselective...
