"could 5-hydroxytryptophan ever be isomerized into 4-hydroxytryptophan?"
NO, NO, NO, NO
If you don't have a clue, then post in the """NEWBEE""" forum. Tell me how you would isomerize it? What reagents would make this transformation?
"or is it more applicable to begin from tryptophan (tryptamine)?"
Yes
"so when it goes dimethyl it will be 4-oh dmt(psylocin)?"
If that is what you want then grow some mushrooms. If DMT is what you want then research extracting it from plant based sources.
