of polymer-supported Lewisbases such as PEG4600-(PPh2)2 and poly(DMAP) in the Baylis–Hillman reactions of N-tosylimines (ArCHNTs) 1 or the corresponding arenecarbaldehydes with α,β-unsaturated ketones has been investigated. The corresponding Baylis–Hillman adducts are obtained in good yields. The polymer-supported Lewisbases can be easily recovered by filtration and the Lewis base PEG4600-(PPh2)2
