Chemoselective palladium-catalyzed α-allylation of α-boryl aldehydes

Herein we report the development of an alpha-allylation reaction of alpha-boryl aldehydes that preserves the carbon-boron bond under Pd-0/Pd-II catalysis. Avariety of alpha-boryl aldehydes and allylic alcohols participate in this chemoselective transformation. The alpha-allylated products were obtained as single regioisomers.
