Brønsted Acid Catalyzed Asymmetric Propargylation of Aldehydes

Which gets activated? A versatile and highly enantioselective chiral Brønsted acid catalyzed method for the propargylation of aldehydes is described to provide a range of chiral homopropargylic alcohols. Computational studies support the belief that the chiral phosphoric acid activates the allenyl b...

description Which gets activated? A versatile and highly enantioselective chiral Brønsted acid catalyzed method for the propargylation of aldehydes is described to provide a range of chiral homopropargylic alcohols. Computational studies support the belief that the chiral phosphoric acid activates the allenyl boronic acid pinacol ester reagent rather than the aldehyde.
