I try to do intramolecular allylic substitution (Tsuji-Trost) of malonamide containing also allylic acetate moiety (-CH(OAc)-CH=CH2). But allylic acetate seems to be unreactive towards palladium catalyst. I tried many conditions (including application of electron-rich phosphines as TTMPP), but never got traces of product. I think allylpalladium complex is not formed in this case.
What's going on? Can allylic acetates behave in such way?
