We report the first example of enantioselective and diastereoselective aldehyde additions of propargyl acetate to aldehydes using the methodology recently reported from our laboratories. Subsequent O-silyl protection, Pd-catalyzed isomerization, AcOH addition, and hydrolysis result in optically active γ-hydroxy α,β-unsaturated aldehydes as powerful building blocks.
