83077-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83077-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,7 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83077-18:
(7*8)+(6*3)+(5*0)+(4*7)+(3*7)+(2*1)+(1*8)=133
133 % 10 = 3
So 83077-18-3 is a valid CAS Registry Number.

Palladium(II)-catalyzed 1,3-dipolar cycloaddition of nitrones with enol ethers

Hori, Kazushige,Ito, Junji,Ohta, Tetsuo,Furukawa, Isao

, p. 12737 - 12744 (2007/10/03)

The 1,3-dipolar cycloadditions of enol ethers as electron-rich olefins with C-phenyl-N-alkyl nitrones proceeded smoothly in the presence of easy handling palladium(II) catalysts under mild conditions to give isoxazolidines in good yield.

1,3-Dipolar cycloaddition reactions of nitrones with alkyl vinyl ethers catalyzed by chiral oxazaborolidines

Seerden, Jean-Paul G.,Boeren, Mike M. M.,Scheeren, Hans W.

, p. 11843 - 11852 (2007/10/03)

The 1,3-dipolar cycloaddition reactions of various Z- and E-nitrones with ethyl vinyl ether and 2,3-dihydrofuran are catalyzed by 20 mol% of chiral oxazaborolidines at room temperature. The effect of high pressure on these reactions is discussed.

Tricarbonyl(benzaldehyde)chromium(0) complexes in organic synthesis: A highly stereoselective 1,3-dipolar cycloaddition of chromium(0)-complexed nitrones

Mukai, Chisato,Cho, Won Jea,Kim, In Jong,Hanaoka, Miyoji

, p. 6893 - 6896 (2007/10/02)

The 1,3-dipolar cycloaddition of chromium(0)-complexed nitrones (10, 11) with electron-rich olefins (2) provided, after decomplexation with CAN, cis-3,5-disubstituted isoxazolidines (cis-14, 15) in a highly stereoselective as well as regioselective manner
