Development of the First Menthane‐Based Chiral Bis(π‐allylpalladium) Catalysis: Asymmetric Allylation of Imines

A new ethylidene menthane‐based chiral π‐allylpalladium complex catalyzes the asymmetric allylation of various imines with allyltributylstannane and 1 equiv. of water to give chiral homoallylamines in good yields and enantioselectivities. The reaction was carried out essentially under neutral conditions and displayed a good transfer of chiral information from the menthane skeleton through the formation of a bis(π‐allylpalladium) species. This is the first example of menthane‐based chiral bis(π‐allylpalladium) catalysis.
