Can someone help me out on this one: How potent is the tropinone based fentanyl analog? What is the ED50? How potent is it, compared to fentanyl?
I guess if one would use phenethylamine instead of methylamine in the Robinson synthesis of tropinone, one would get a usefull tropinone based fentanyl precursor. Am I right?
