17276-03-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17276-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,7 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17276-03:
(7*1)+(6*7)+(5*2)+(4*7)+(3*6)+(2*0)+(1*3)=108
108 % 10 = 8
So 17276-03-8 is a valid CAS Registry Number.

A metalation strategy for the construction of functionalized naphthalenes: The first synthesis of guieranone A

McCulloch, Malcolm W.B.,Barrow, Russell A.

, p. 7619 - 7621 (2005)

The first synthesis of the natural product guieranone A is described, demonstrating a one-pot procedure for the synthesis of protected-1,3,6,8- tetraoxygenated naphthalenes and a subsequent directed metalation synthesis of 2-keto naphthalenes.

Mild aromatic palladium-catalyzed protodecarboxylation: Kinetic assessment of the decarboxylative palladation and the protodepalladation steps

Dickstein, Joshua S.,Curto, John M.,Gutierrez, Osvaldo,Mulrooney, Carol A.,Kozlowski, Marisa C.

, p. 4744 - 4761 (2013/07/11)

Mechanism studies of a mild palladium-catalyzed decarboxylation of aromatic carboxylic acids are described. In particular, reaction orders and activation parameters for the two stages of the transformation were determined. These studies guided development of a catalytic system capable of turnover. Further evidence reinforces that the second stage, protonation of the arylpalladium intermediate, is the rate-determining step of the reaction. The first step, decarboxylative palladation, is proposed to occur through an intramolecular electrophilic palladation pathway, which is supported by computational and mechanism studies. In contrast to the reverse reaction (C-H insertion), the data support an electrophilic aromatic substitution mechanism involving a stepwise intramolecular protonation sequence for the protodepalladation portion of the reaction.

Carbocations in action. Design, synthesis, and evaluation of a highly acid-sensitive naphthalene-based backbone amide linker for solid-phase synthesis

Pittelkow, Michael,Boas, Ulrik,Christensen, Jorn B.

, p. 5817 - 5820 (2007/10/03)

(Diagram presented) The design, synthesis, and properties of an extremely acid-labile backbone amide linker based on a regiospecifically substituted tetraalkoxy naphthaldehyde core are presented. This handle enables cleavage of peptide backbone amides (se
