Strike while the iron is hot: A temperature‐guideddiastereoselectivityswitch has been observed in the desymmetrization of meso‐7‐azabicyclic alkadiene. Both enantiomeric forms of this bicyclic structural framework are formed by using either of the enantiomers of hydrobenzoin (see scheme; Boc=tert‐butyloxycarbonyl).
