Aza‐Baylis–Hillman reactions of β‐substituted activated olefins such as crotonaldehyde, ( E )‐propenyl phenyl ketone, hex‐2‐enal or pent‐3‐en‐2‐one with N ‐tosyl imines can be carried out for the first time in the presence of tertiary phosphine Lewis bases such as PPh 2 Me or PPhMe 2 to give the corresponding Baylis–Hillman adducts in moderate to good yields under mild reaction conditions.
