22760-66-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22760-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,7,6 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22760-66:
(7*2)+(6*2)+(5*7)+(4*6)+(3*0)+(2*6)+(1*6)=103
103 % 10 = 3
So 22760-66-3 is a valid CAS Registry Number.

Copper-catalyzed chemoselective cross-coupling reaction of thioamides and α-diazocarbonyl compounds: Synthesis of enaminones

The development of operationally simple and cost-effective methods for C[sbnd]C bond formation reactions are highly important in pharmaceutical, agrochemical and material research. In this article we describe the first copper-catalyzed cross-coupling reaction of thioamides with acceptor/acceptor-substituted and acceptor-only substituted α-diazocarbonyl compounds to yield enaminones. The reaction shows broad substrate scope in terms of thioamides and diazocarbonyl compounds. Primary, secondary and tertiary thioamides all give enanminones when reacted with α-diazodiesters, α-diazoketoesters, α-diazodiketones, α-diazoketoamides, α-diazoesteramides, α-diazoketosulfones and α-diazomonoketones.

New 1-[quinolyl(4)]-1,2,3-triazoles: Synthesis and evaluation of antiinflammatory and analgesic properties. III

Savini,Massarelli,Chiasserini,Pellerano,Bruni

, p. 633 - 639 (2007/10/02)

Several 1-[quinolyl(4)]-1,2,3-triazoles were synthesized by 1,3-dipolar cycloaddition of 4-azidoquinolines with activated methylene compounds. The synthesized compounds, tested for antiinflammatory and analgesic activities, resulted moderately active as antiinflammatories, but with a very interesting analgesic activity, sometimes higher than that of indomethacin, used as reference drug. Some of the triazole derivatives were evaluated also as antimicrobial, but none of them exhibited activity.
