In control: By controlling the kinetics of alkynylation over aldolization, the challenging asymmetriccatalyticalkynylation of acetaldehyde has been realized. The resulting products are attractive synthons which are produced with good to excellent enantiocontrol, and show broad tolerance and applicability, as demonstrated by the synthesis (+)‐tetrahydropyrenophorol.
