104819-24-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104819-24-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,1 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104819-24:
(8*1)+(7*0)+(6*4)+(5*8)+(4*1)+(3*9)+(2*2)+(1*4)=111
111 % 10 = 1
So 104819-24-1 is a valid CAS Registry Number.

Palladium-catalyzed intramolecular decarboxylative allylic arylation of α-aryl-γ-methylidene-δ-valerolactones

Shintani, Ryo,Tsuji, Takaoki,Park, Soyoung,Hayashi, Tamio

supporting information; experimental part, p. 1697 - 1699 (2010/07/07)

A palladium-catalyzed intramolecular decarboxylative cyclization of α-aryl-γ-methylidene-δ-valerolactones, followed by olefin isomerization, has been developed to give fused polycyclic aromatic compounds under mild conditions. The process described here can be regarded as a formal decarboxylative allylic arylation without using a pre-formed organometallic nucleophile. The reaction can be conducted on a gram scale and the products thus obtained are further derivatized with ease.

REACTIONS OF β-KETO ESTERS WITH 2-CYANO-1,2,5,6-TETRAHYDROPYRIDINES

Chapman, R. F.,Phillips, N. I. J.,Ward, R. S.

, p. 5229 - 5234 (2007/10/02)

Reaction of the sodium salts of β-keto esters 13a and 13b with the 2-cyano-tetrahydropyridines 11 and 12 afforded the 4-substituted piperidine derivatives 21-23.The structures were assigned on the basic of their (1)H-and (13)C-NMR spectra and by comparison with the model compounds 24-26.The stereochemistry and the mechanism of the reactions are discussed.
