A gold catalyst promotes the sequential cleavage of the S−O and N−S bonds of a sulfinyl group, leading to S‐functionalized azirines. As Itaru Nakamura et al. illustrate in their Communication on page 12248, the transformation is like making plastic models: A golden diagonal plier cuts these bonds, and the cut out parts are assembled into the product using an alkyne triple bond unit. Substituents in the product can be chosen from the kit as desired.
