24423-93-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24423-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,2 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24423-93:
(7*2)+(6*4)+(5*4)+(4*2)+(3*3)+(2*9)+(1*3)=96
96 % 10 = 6
So 24423-93-6 is a valid CAS Registry Number.

Stereochemistry of 1,3-dipolar cycloadditions of nitrones with (E)-1-alkyl-2-nitroethenes

Yakura,Nakazawa,Takino,Ikeda

, p. 2014 - 2018 (1992)

1,3-Dipolar cycloadditions of the C-aryl-N-alkylnitrones 2a-c and the C,N-dialkylnitrones 2e-g with the (E)-1-alkyl-2-nitroethenes 1a,b afforded predominantly or exclusively the cis-3-substituted 4-nitroisoxazolidines 3a-d and 3f-h. Exceptions are the rea

Enantioselective nitrone cycloadditions of α,β-unsaturated 2-acyl imidazoles catalyzed by bis(oxazolinyl)pyridine-cerium(IV) triflate complexes

Evans, David A.,Song, Hyun-Ji,Fandrick, Keith R.

, p. 3351 - 3354 (2007/10/03)

Enantioselective nitrone cycloadditions with β-substituted α,β-unsaturated 2-acyl imidazoles catalyzed by bis(oxazolinyl) pyridine-cerium(IV) triflate complexes 1 have been reported. The isoxazolidine products were efficiently transformed into densely functionalized β′-hydroxy-β-amino acid derivatives.

Selective Rhodium-Catalyzed Insertion of Carbon Monoxide into the Nitrogen-Oxygen Bond of Isoxazolidines. New Reduction, Migration, and Rearrangement Reactions Catalyzed by Iridium Complexes

Khumtaveeporn, Kanjai,Alper, Howard

, p. 8142 - 8147 (2007/10/02)

Reaction of isoxazolidines with carbon monoxide in benzene, catalyzed by the dimer of chloro(1,5-cyclooctadiene)rhosium, results in the formation of tetrahydro-1,3-oxazin-2-ones as the major or only product, often in fine yields.A novel conversion of 3-ar
