Amfetaminil (also known as amphetaminil, N-cyanobenzylamphetamine,[1] and AN-1; brand name Aponeuron) is a stimulant drug derived from amphetamine, which was developed in the 1970s and used for the treatment of obesity,[2] ADHD,[3][4] and narcolepsy.[5] It has largely been withdrawn from clinical use following problems with abuse.[6] The drug is a prodrug to amphetamine.[7][8]
Stereochemistry
Amfetaminil is a molecule with two stereogenic centers. Thus, four different stereoisomers exist:
(R)-2-[(R)-1-Phenylpropan-2-ylamino]-2-phenylacetonitrile (CAS number 478392-08-4)
(S)-2-[(S)-1-Phenylpropan-2-ylamino]-2-phenylacetonitrile (CAS number 478392-12-0)
(R)-2-[(S)-1-Phenylpropan-2-ylamino]-2-phenylacetonitrile (CAS number 478392-10-8)
(S)-2-[(R)-1-Phenylpropan-2-ylamino]-2-phenylacetonitrile (CAS number 478392-14-2)
Synthesis
Schiff base formation between amphetamine (1) and benzaldehyde (2) gives benzalamphetamine [2980-02-1] (3). Nucleophilic attack of cyanide anion on the imine (c.f. Strecker reaction) gives amfetaminil (4). Finally, reaction with nitrous acid gives (5). The rearrangement to a Sydnone then occurs to give CID:88166659 (6). Feprosidnine is sans the phenyl group.
