Abstract
Acetates of Baylis-Hillman adducts derived from ethyl acrylate, methyl vinyl ketone, and acrylonitrile were coupled with allyltributylstannane using Pd(PPh3)4 or Pd(dba)2 as the catalyst at room temperature to afford the corresponding trisubstituted alka-1,5-dienes in good to high yields.
Key words
Baylis-Hillman acetates - allyltributylstannane - bis-π-allylpalladium - 1,5-diene - allylation
