87797-13-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87797-13-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,9 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87797-13:
(7*8)+(6*7)+(5*7)+(4*9)+(3*7)+(2*1)+(1*3)=195
195 % 10 = 5
So 87797-13-5 is a valid CAS Registry Number.

Visible-Light-Mediated [4+2] Cycloaddition of Styrenes: Synthesis of Tetralin Derivatives

Wang, Leifeng,Wu, Fengjin,Chen, Jiean,Nicewicz, David A.,Huang, Yong

supporting information, p. 6896 - 6900 (2017/06/08)

We report a formal [4+2] cycloaddition reaction of styrenes under visible-light catalysis. Two styrene molecules with different electronic or steric properties were found to react with each other in good yield and excellent chemo- and regioselectivity. This reaction provides direct access to polysubstituted tetralin scaffolds from readily available styrenes. Sophisticated tricyclic and tetracyclic tetralin analogues were prepared in high yield and up to 20/1 diasteroselectivity from cyclic substrates.

Ring selectivity in the Na/EtOH reduction of 1-aryl-7-methoxynaphthalenes

Carre?o, M. Carmen,González-López, Marcos,Latorre, Alfonso,Urbano, Antonio

, p. 1601 - 1605 (2007/10/03)

Na/EtOH reduction of 1-aryl-7-methoxynaphthalenes occurred preferentially at the A-ring when no substituents were present at the ortho-positions of the aryl group (up to 100% selectivity), to afford 1-aryl-7-methoxy-1,2,3,4- tetrahydronaphthalenes. Ortho-

An approach to the biomimetic synthesis of aryltetralin lignans

Pelter, Andrew,Ward, Robert S.,Rao, Ramohan R.

, p. 2933 - 2938 (2007/10/02)

The BF3 catalysed cyclisation of 3-arylpropyl substituted quinone-methide ketals affords a mild, biomimetic route to aryltetralins. 1H- and 13C-NMR spectra of the products are reported.
