Yes,
   
  It is highly possible because tetrasubstituted double bond is much more difficult to be reduced. The pressure of hydrogen and the load of Pd catalyst could play the trick.
   
  Good luck!

    hi folks:
   
  Is it possible to selectively hydrogenate a di-substituted alkenyl part over a tetrasubstituted alkenyl part in a same molecule (or a same macrolide ring), using palladium catalyst, like Pd-C?
   
  Thanks!!
