389079-71-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 389079-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,0,7 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 389079-71:
(8*3)+(7*8)+(6*9)+(5*0)+(4*7)+(3*9)+(2*7)+(1*1)=204
204 % 10 = 4
So 389079-71-4 is a valid CAS Registry Number.

Aza-heterocycles via copper-catalyzed, remote C–H desaturation of amines

Dare, Ross M.,Nagib, David A.,Paneque, Alyson N.,Stateman, Leah M.

supporting information, p. 210 - 224 (2022/01/19)

A majority of medicines contain a nitrogen atom within a five- or six-membered ring. To rapidly access both such aza-heterocycles, we sought to develop a remote C–H desaturation of amines. Inspired by the Hofmann-L?ffler-Freytag (HLF) synthesis of five-me

Iridium-Catalyzed Cycloisomerization of N-Tethered 1,7-Enynes: Construction of an Azabicyclo[5.1.0]octene System

Zhao, Sheng,Zang, Zhong-Lin,Li, Siyu,Wen, Xumei,Wang, Chenhui,Guo, Jian,He, Yun

, p. 9321 - 9330 (2020/08/14)

An efficient method for the synthesis of azabicyclo[5.1.0]octenes through cycloisomerization of nitrogen-tethered 1,7-enynes catalyzed by [IrCp*Cl2]2 was developed. With appropriately designed substrates, this method could be easily employed to generate complex fused ring systems such as [6-6-3-7], [5-6-3-7], [7-6-3-7], and [8-6-3-7] ring systems, which enriches the diversity of the cyclopropane-fused polycycle library, and has potential applications in SAR studies of pharmaceutically interesting compounds and total synthesis of natural products.

DIRECT ANTI-MARKOVNIKOV ADDITION OF ACIDS TO ALKENES

-

Paragraph 0069; 0070; 0071; 0098; 0099, (2016/05/02)

A method of making an anti-Markovnikov addition product, comprises reacting an acid with an alkene or alkyne in a dual catalyst reaction system to the exclusion of oxygen to produce said anti-Markovnikov addition product; the dual catalyst reaction system comprising a single electron oxidation catalyst in combination with a hydrogen atom donor catalyst. Dual catalyst composition useful for carrying out such methods are also described.
