This approach may not be too promising. Further simplifying the molecule as shown gives the known alkaloid hordenine, which is toxic. See https://en.wikipedia.org/wiki/Hordenine

not really! depend how you go about doing it.. (here is one easy way with a phenolic ketone No need to protect the phenol !..but no synthesis talk on BL tho. (@mod: remove if inappropriate)Now add amino alfa to the ketone (very easy to do) you get this:
I don't agree. You will have to protect/deprotect that phenol group before you can add that amino function so it becomes a multi-step problem.
What is the function of Phenolic OH in morphine?
Hydrogen bond donator, or acceptor? I guess the former, since codeine is much weaker.
Or is there another binding mode of that OH?
doesnt look like any disso one can think of
