Efficient in-loop synthesis of high specific radioactivity [ 11C]carfentanil
Studenov, Andrei R.,Jivan, Salma,Buckley, Kenneth R.,Adam, Michael J.
, p. 837 - 842 (2003)
The synthesis of the precursor for [11C]carfentanil and the precursor labelling with 11C have both been improved. The problem 'bottleneck' step in the carfentanil precursor synthesis, due to low chemical yield (14%) of intermediates

An improved process or method of synthesis of carfentanil and other potent opioid analgesics of the N-alkyl 4-substituted 4-piperidinylamide class which can be used as morphine substitutes.
Synthesis of 4-anilinopiperidine methyl esters, intermediates in the production of carfentanil, sufentanil, and remifentanil
Walz, Andrew J.,Hsu, Fu-Lian
supporting information, p. 501 - 502 (2014/01/06)
Two spirodiaza intermediates have been made and employed in the synthesis of 4-anilinopiperidine methyl esters. These intermediates can be utilized in the production of commercial synthetic analgesics carfentanil, sufentanil, and remifentanil.
