ChemInform Abstract: Synthesis and X‐Ray Crystal Structures of Isonipecotinamide Derivatives as Reverse Amide Analogues of Fentanyl.

Abstract

AbstractThe isonipecotinamide derivatives (II), (VIII) and (IX) (obtained similarly to (VIII)), which represent reverse amide derivatives of the potent analgetic fentanyl (III), are evaluated for analgetic activity.
