1-Ethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepine is a chemical compound with the molecular formula C11H15N. It is a derivative of benzo[b]azepine, a heterocyclic compound consisting of a benzene ring fused to a seven-membered azepine ring. The presence of a tetrahydro group indicates that four hydrogen atoms are added to the molecule, reducing the number of double bonds and increasing the saturation level. The ethyl group (C2H5) is attached to the nitrogen atom in the azepine ring, making it a substituted derivative. 1-ethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepine is of interest in medicinal chemistry due to its potential applications as a precursor in the synthesis of various pharmaceuticals and as a ligand in coordination chemistry. Its structure and properties make it a versatile building block for the development of new drugs and materials.

3649-17-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3649-17-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3649-17:
(6*3)+(5*6)+(4*4)+(3*9)+(2*1)+(1*7)=100
100 % 10 = 0
So 3649-17-0 is a valid CAS Registry Number.

Sodium Triethylborohydride-Catalyzed Controlled Reduction of Unactivated Amides to Secondary or Tertiary Amines

Yao, Wubing,He, Lili,Han, Deman,Zhong, Aiguo

, (2019)

The first transition-metal-free catalytic protocol for controlled reduction of amide functions using cheap and bench-stable hydrosilanes as reducing agents has been established. By altering the hydrosilane and solvent, the new method enables the selective cleavage of unactivated C-O bonds in amides and allows the C-N bonds to selectively break via the deacylated cleavage. Overall, this novel process may offer a versatile alternative to current methodologies employing stoichiometric metal systems for the controlled reduction of carboxamides.

Novel nonmetal catalytic bidirectional selective reduction method of tertiary aromatic amide

-

Paragraph 0098; 0099; 0100; 0101, (2017/10/22)

The invention relates to a novel effective bidirectional selective environment-friendly method for hydrosilation reduction of tertiary aromatic amide and an organic silicon reagent. The method comprises the following steps: selecting a nonmetal catalytic system, and selectively preparing a secondary or tertiary organic amine compound by successively catalyzing tertiary aromatic amide and cheap PHMS or triethoxysilane under a mild condition. By adopting the method, the bidirectional selective reduction of the tertiary aromatic amide is realized by innovatively utilizing an electronic effect and steric hindrance difference of an organic silicon reagent at first time, so that a brand new strategy is provided for the reduction of amide and derivative of the amide, the defects of the traditional method that the substrate functional group is poor in compatibility, the production cost is high and the like can be overcome, and the application prospect of the amine compound prepared in industrial production or laboratory is promising.
