11-Methyldibenz[b,f][1,4]oxazepine, also known as Carfentanil, is a potent synthetic opioid analgesic chemically related to the well-known painkiller Fentanyl. It is approximately 10,000 times more potent than morphine and is used primarily in veterinary medicine for immobilizing large animals such as elephants. Due to its extreme potency and potential for abuse, Carfentanil is classified as a Schedule II controlled substance in the United States. It is not intended for human use and poses significant risks if ingested or inhaled, as even a small amount can be lethal.

2868-49-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2868-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2868-49:
(6*2)+(5*8)+(4*6)+(3*8)+(2*4)+(1*9)=117
117 % 10 = 7
So 2868-49-7 is a valid CAS Registry Number.

Asymmetric Hydrogenation of Seven-Membered C=N-containing Heterocycles and Rationalization of the Enantioselectivity

Balakrishna, Bugga,Bauzá, Antonio,Frontera, Antonio,Vidal-Ferran, Anton

supporting information, p. 10607 - 10613 (2016/07/21)

Iridium(I) complexes with phosphine–phosphite ligands efficiently catalyze the enantioselective hydrogenation of diverse seven-membered C=N-containing heterocyclic compounds (eleven examples; up to 97 % ee). The P-OP ligand L3, which incorporates an ortho

Microwave-assisted synthesis of substituted dibenzo[b,f][1,4]thiazepines, dibenzo[b,f][1,4]oxazepines, benzothiazoles, and benzimidazoles

Lin, Yu-Chin,Li, Ni-Ching,Cherng, Yie-Jia

, p. 808 - 814 (2014/06/10)

A highly efficient synthesis for possessing 7-membered rings with two heteroatoms is described, using efficient microwave-assisted one-pot method to synthesize (substituted) dibenzo[b,f][1,4]thiazepines [1] and dibenzo[b,f][1,4]oxazepines [2] in high yields (up to 99%) by cyclocondensations of o-aminothiophenol or o-aminophenol with o-halobenzaldehydes, o-fluoroacetophenone, and o-fluorobenzophenone. In the absence of base, o-aminothiophenol reacted with o-halobenzaldehydes to afford benzothiazoles.

Synthesis and enantioselective hydrogenation of seven-membered cyclic imines: Substituted dibenzo[b,f][1,4]oxazepines

Gao, Kai,Yu, Chang-Bin,Li, Wei,Zhou, Yong-Gui,Zhang, Xumu

supporting information; experimental part, p. 7845 - 7847 (2011/09/13)

Highly enantioselective hydrogenation of seven-membered cyclic imines, substituted dibenzo[b,f][1,4]oxazepines, was achieved, with up to 94% ee, by using the [Ir(COD)Cl]2/(S)-Xyl-C3*-TunePhos complex as the catalyst in the presence of morpholine-HCl.
