38491-47-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38491-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,9 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 38491-47:
(7*3)+(6*8)+(5*4)+(4*9)+(3*1)+(2*4)+(1*7)=143
143 % 10 = 3
So 38491-47-3 is a valid CAS Registry Number.

Modulating N- versus O-arylation in pyrazolone-aryl halide couplings

Golden, Jennifer E.,Sanders, Shanina D.,Muller, Kristine M.,Bürli, Roland W.

, p. 794 - 798 (2008)

The regioselective, copper-catalyzed coupling of a tautomeric pyrazolone/pyrazole with 2-halopyridines was investigated. Conditions were developed to preferentially form either the N-aryl or O-aryl product.

Development of Gold-catalyzed [4+1] and [2+2+1]/[4+2] Annulations between Propiolate Derivatives and Isoxazoles

Sahani, Rajkumar Lalji,Liu, Rai-Shung

supporting information, p. 1026 - 1030 (2017/01/18)

Two new gold-catalyzed annulations of isoxazoles with propiolates have been developed. Most isoxazoles follow an initial O attack on the alkyne to afford a [4+1] annulation product. This process results in a remarkable alkyne cleavage of initial propiolates. Unsubstituted isoxazoles proceed through an N attack step to yield formal [2+2+1]/[4+2] annulation products. These two annulation products arise initially from two seven-membered heterocyclic intermediates, which then lead to products.

Gold-catalyzed formal [4π+2π]-cycloadditions of tert-butyl propiolates with aldehydes and ketones to form 4H-1,3-dioxine derivatives

Karad, Somnath Narayan,Chung, Wei-Kang,Liu, Rai-Shung

supporting information, p. 13004 - 13007 (2015/08/06)

Gold-catalyzed formal hetero-[4π+2π] cycloadditions of tert-butyl propiolates with carbonyl compounds proceeded efficiently to yield 4H-1,3-dioxine derivatives over a wide scope of substrates. With acetone as a promoter, gold-catalyzed cycloadditions of these propiolate derivatives with enol ethers led to the formation of atypical [4+2]-cycloadducts with skeletal rearrangement.

Copper-catalyzed domino route to natural nostoclides and analogues: A total synthesis of nostoclides i and II

Ngi, Samuel Inack,Petrignet, Julien,Duwald, Romain,El Hilali, El Mostafa,Abarbri, Mohamed,Duchêne, Alain,Thibonnet, Jér?me

supporting information, p. 2936 - 2941 (2014/03/21)

An original and convenient domino route to natural nostoclides I and II has been developed using a two-step sequence consisting of a copper-cat-alyzed tandem reaction associated with Suzuki cross-coupling. The methodology employed for this total synthesis appeared to be an interesting and suffi-ciently flexible tool to allow the synthesis of numer-ous analogues of these nostoclides.
