Because of such harsh conditions, this reaction doesn't seem to be a viable option for P2P synthesis, and most certainly not for MDP2P, because the needed starting compound is very hard to manufacture, and the harsh conditions would likely destroy the ring anyway.
Now I see why this hasn't been discussed.
