Gupta fentanyl synthesis
Webother methods to synthesize fentanyl, one of which is known as the Gupta method. 4-Piperidone can be used to synthesize 4-anilinopiperidine, a list I chemical under the CSA8 and key precursor in the Gupta method. 4-Anilinopiperidine serves as an alternative precursor chemical to NPP in the synthesis of ANPP, albeit through a different synthetic Websynthetic route for parent fentanyl 4 along with additional analogs. The routes described herein were optimized to obtain fentanyls in high yields using an efficient, three-step synthetic strategy. The four analogs that our efforts focused on are: fentanyl (4), acetylfentanyl (9), thiofentanyl (10) and acetylthiofentanyl (11).

WebNational Center for Biotechnology Information Fentanyl is a 4-anilopiperidine class synthetic opioid. The synthesis of Fentanyl is accomplished by one of four main methods as reported in scientific literature: the Janssen, Seigfried, Gupta, or Suh method. The original synthesis as patented in 1964 by Dr. Paul Janssen involves synthesis of benzylfentanyl from N-Benzyl-4-Piperidone. The resulting benzylfe…
