Fentanyl synthesis

Essawi, M.Y.H. Fentanyl analogues with a modified propanamido group as potential affinity labels Synthesis and in vivo activity, Pharmazie 1999, 54, 307-308. 

The l-methyl-3-allyl congener of fentanyl was made by application of the routine synthesis to l-methyl-3-allyl-4-piperidone (p.267) while l-carbethoxy-3-allyl-4-piperidone served as intermediate for synthesis of the 3-allyl/propyl-N-phenethyl analogs (Scheme 8.1). Reduction of intermediate Schiff bases was highly stereoselective and the cis isomers were produced almost exclusively by both chemical and catalytic reduction procedures low yields of the 3-propyl...

Understanding the neurochemistry of these compounds has led to the synthesis and availability of several useful drugs. Fentanyl is a common narcotic pain reliever used in surgical procedures, and sumatriptan (trade name Imitrex) is used to relieve pain and light sensitivity in patients who suffer from migraine headaches. 

Inhibition of cell growth and DNA, RNA, and protein synthesis in vitro by fentanyl, sufentanil, and opiate analgesics Nassiri, M. Reza Flynn, Gordon L. Shipman, Charles, Jr. 

The piperidine ring is probably the most common heterocycle occurring in pharmaceuticals. Piperidine is often used as a secondary amine in the synthesis of drugs. The local anaesthetic bupivacaine 20 (used as the racemate or the ( S)-enantiomer levobupivacaine) is a pipecolinic acid derivative. The antihistamine bamipine 21 and the analgesic fentanyl 22 are derived from 4-aminopiperidines. The ... 

What are the merits and demerits of Basal Anaesthetics " Describe the synthesis of the following (i) Fentanyl citrate ii) Tribromoethanol (in) Paraldehyde. 

Scheme 33 A Structures of the synthetic opioids fentanyl (165), carfentanil (166) and sufentanil (167), B Synthesis of the synthetic opioid alfentanil (172) [128]...

Fentanyl is a nonopoid (nonmorphinelike) analgesic used for the relief of severe pain. It is approximately 50 times more potent in humans than morphine itself. One synthesis for fentanyl begins with 2-phenylethanamine ...
