There is a speciality material called Apritone, but I don't know if it commercially available. And a base called Nectaryl (can't remember who makes it). A touch of Buccu or Cassis would also help. I see you mean about Oud; there is a leathery animalic aspect to Osmanthus. Chinese Cedarwood could be useful. Anything ussed to make Leather accord (iso Butyl Quinolene and Birch Tar, in very small amounts).
Very sound advice here, just to add that I've seen Apritone
listed by Bedoukian though I've never used it.Nectaryl
is available at a reasonable price - it is made by Givaudan - and has a lovely peachy note that is almost good enough to be a peach accord on its own.
