Allylic phosphates 482 Subject

Various new methods for achieving allylic substitution have emerged this year. It is interesting to note that allylic phosphates may be subjected to allylic displacement with nucleophiles in the presence of [PdCPhgP) ]. Moreover, the allylic function may be selectively displaced in the presence of an allylic acetate hence sequential alkylations/aminations are possible. Two reports have also discussed the use of allylic nitro-compounds in similar reactions. As the nitro-starting materials for these reactions are available by a variety of methods, the procedure further extends the use of 7r-allylpalladium complexes in organic synthesis.
