38454-62-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38454-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,5 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 38454-62:
(7*3)+(6*8)+(5*4)+(4*5)+(3*4)+(2*6)+(1*2)=135
135 % 10 = 5
So 38454-62-5 is a valid CAS Registry Number.

A catalytic diastereoselective formal [5+2] cycloaddition approach to azepino[1,2-a]indoles: Putative donor-acceptor cyclobutanes as reactive intermediates

Shenje, Raynold,Martin, M. Cynthia,France, Stefan

, p. 13907 - 13911 (2014)

A catalytic formal [5+2] cycloaddition approach to the diastereoselective synthesis of azepino[1,2-a]indoles is reported. The reaction presumably proceeds through a Lewis acid catalyzed formal [2+2] cycloaddition of an alkene with an N-indolyl alkylidene b-amide ester to form a donor-acceptor cyclobutane intermediate, which subsequently undergoes an intramolecular ring-opening cyclization. Azepine products are formed in up to 92% yield with high degrees of diastereose-lectivity (up to 34:1 d.r.).

Iron Catalyzed Isomerization of α-Alkyl Styrenes to Access Trisubstituted Alkenes

Xu, Songgen,Liu, Guixia,Huang, Zheng

, p. 585 - 589 (2021/02/01)

Stereoselective isomerization of α-alkyl styrenes is accomplished using a new iron catalyst supported by phosphine-pyridine-oxazoline (PPO) ligand. The protocol provides an atom-efficient and operationally simple approach to trisubstituted alkenes in high

Cobalt-Catalyzed Migrational Isomerization of Styrenes

Zhao, Jiajin,Cheng, Biao,Chen, Chenhui,Lu, Zhan

supporting information, p. 837 - 841 (2020/01/31)

An efficient cobalt-catalyzed migrational isomerization of styrenes was developed using the thiazoline iminopyridine (TIP) ligand. This reaction is operationally simple and atom-economical using readily available starting materials to access trisubstituted alkenes. Even when using a 0.1 mol % catalyst loading, the reaction could be conducted in neat and completed in 1 h with excellent conversion and high E stereoselectivity.
