113085-39-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113085-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,0,8 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113085-39:
(8*1)+(7*1)+(6*3)+(5*0)+(4*8)+(3*5)+(2*3)+(1*9)=95
95 % 10 = 5
So 113085-39-5 is a valid CAS Registry Number.

Mild chemo-enzymatic synthesis of polymer-supported cinchona alkaloids and their application in asymmetric Michael addition

Athawale, Vilas,Manjrekar, Narendra

, p. 4541 - 4543 (2001)

Cinchona alkaloid (CA) monomers were synthesised enzymatically in high yield (90%) by selectively acrylating the primary -OH group of the CA, and the co-polymers obtained with acrylonitrile were tested for their efficiency for asymmetric induction in Mich

Enantioselective conjugate addition of thiols to cyclic enones and enals catalyzed by chiral N,N'-dioxide-cadmium iodide complex

Saito, Makoto,Nakajima, Makoto,Hashimoto, Shunichi

, p. 9589 - 9594 (2000)

Chiral N,N'-dioxide-cadmium iodide complex has been shown to catalyze enantioselective conjugate additions of thiols to cyclic enones and enals. The sulfides are generated in high yields and in good enantioselectivities up to 78% ee using 1 mol% of the chiral catalyst. The present reaction provides the first example of utilizing a cadmium complex as a catalyst in enantioselective reaction. (C) 2000 Elsevier Science Ltd.

Enantioselective conjugate addition of thiols to enones and enals catalyzed by chiral N-oxide-cadmium complex

Saito,Nakajima,Hashimoto

, p. 1851 - 1852 (2000)

A novel method of enantioselective conjugate addition of thiols to enones and enals produces sulfides with enantio-selectivities up to 78% ee, employing a cadmium complex of (S)-3,3'-dimethyl-2,2'-biquinoline N,N'-dioxide 1 as a catalyst.

Combined bead polymerization and Cinchona organocatalyst immobilization by thiol-ene addition

Fredriksen, Kim A.,Kristensen, Tor E.,Hansen, Tore

experimental part, p. 1126 - 1133 (2012/09/05)

In this work, we report an unusually concise immobilization of Cinchona organocatalysts using thiol-ene chemistry, in which catalyst immobilization and bead polymerization is combined in a single step. A solution of azo initiator, polyfunctional thiol, polyfunctional alkene and an unmodified Cinchona-derived organocatalyst in a solvent is suspended in water and copolymerized on heating by thiol-ene additions. The resultant spherical and gel-type polymer beads have been evaluated as organocatalysts in catalytic asymmetric transformations.

Highly enantioselective organocatalytic sulfa-michael addition to α, β-unsaturated ketones

Rana, Nirmal K.,Selvakumar, Sermadurai,Singh, Vinod K.

supporting information; experimental part, p. 2089 - 2091 (2010/06/16)

"Chemical Equation Presented" A cinchona alkaloid-derived urea was found to be an efficient organocatalyst for catalyzing enantioselective conjugate addition between thiols and various α,β-unsaturated ketones to provide optically active sulfides with high

Asymmetrie ruthenium-catalyzed 1,4-additions of aryl thiols to enones

Badoiu, Andrei,Bernardinelli, Gerald,Besnard, Celine,Peter Kuendig

supporting information; experimental part, p. 193 - 200 (2010/04/25)

Well defined, stable, one-point binding ruthenium complexes 1 and 2 selectively bind and activate α,β-unsaturated carbonyl compounds for cycloaddition reactions. These mild Lewis acids catalyze asymmetric 1,4-addition reactions of aryl thiols to enones wi

DOSY NMR for monitoring self aggregation of bifunctional organocatalysts: Increasing enantioselectivity with decreasing catalyst concentration

Jang, Hyeong Bin,Rho, Ho Sik,Oh, Joong Suk,Nam, Eun Hye,Park, Sang Eun,Bae, Han Yong,Song, Choong Eui

supporting information; experimental part, p. 3918 - 3922 (2010/09/17)

In this report, we demonstrate that self-aggregation is an intrinsic problem of bifunctional organocatalysts, especially in the case when the substrates do not have functional groups which are able to bind strongly with catalyst. Due to their self-associa

Improved design of inherently chiral calix[4]arenes as organocatalysts
