459174-07-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 459174-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,1,7 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 459174-07:
(8*4)+(7*5)+(6*9)+(5*1)+(4*7)+(3*4)+(2*0)+(1*7)=173
173 % 10 = 3
So 459174-07-3 is a valid CAS Registry Number.

The palladium-catalyzed aerobic kinetic resolution of secondary alcohols: Reaction development, scope, and applications

Ebner, David C.,Bagdanoff, Jeffrey T.,Ferreira, Eric M.,McFadden, Ryan M.,Caspi, Daniel D.,Trend, Raissa M.,Stoltz, Brian M.

supporting information; experimental part, p. 12978 - 12992 (2010/06/19)

The first palladium-catalyzed enantioselective oxidation of secondary alcohols has been developed, utilizing the readily available diamine (-)-sparteine as a chiral ligand and molecular oxygen as the stoichiometric oxidant. Mechanistic insights regarding the role of the base and hydrogen-bond donors have resulted in several improvements to the original system. Namely, addition of cesium carbonate and tert-butyl alcohol greatly enhances reaction rates, promoting rapid resolutions. The use of chloroform as solvent allows the use of ambient air as the terminal oxidant at 23°C, resulting in enhanced catalyst selectivity. These improved reaction conditions have permitted the successful kinetic resolution of benzylic, allylic, and cyclopropyl secondary alcohols to high enantiomeric excess with good-toexcellent selectivity factors. This catalyst system has also been applied to the desymmetrization of meso-diols, providing high yields of enantioenriched hydroxyketones.

The resolution of important pharmaceutical building blocks by palladium-catalyzed aerobic oxidation of secondary alcohols

Caspi, Daniel D.,Ebner, David C.,Bagdanoff, Jeffrey T.,Stoltz, Brian M.

, p. 185 - 189 (2007/10/03)

The palladium-catalyzed aerobic oxidative kinetic resolution of key pharmaceutical building blocks is described. Substrates investigated are relevant to the enantioselective preparation of Prozac, Singulair, and the promising hNK-1 receptor antagonist from Merck. The latter provides the most selective aerobic oxidative kinetic resolution yet described.

Asymmetric synthesis of 1,2,3-trisubstituted cyclopentanes and cyclohexanes as key components of substance P antagonists

Kuethe, Jeffrey T.,Wong, Audrey,Wu, Jimmy,Davies, Ian W.,Dormer, Peter G.,Welch, Christopher J.,Hillier, Michael C.,Hughes, David L.,Reider, Paul J.

, p. 5993 - 6000 (2007/10/03)

An efficient asymmetric synthesis of 1,2,3-trisubstituted cyclopentanes and cyclohexanes is described. Three methods were developed for the preparation of the 2,3-disubstituted cyclopentenones and cyclohexenones, which are key achiral building blocks. These intermediates are reduced catalytically with (R)-2-methyloxazaborolidine in high yield (82-98%) and excellent ee (89-96%). Directed reduction of the chiral allylic alcohols using Red-Al gives exclusively the 1,2-anti stereochemistry (>99:1). Epimerization of the ester center followed by saponification/crystallization affords the desired hydroxyacids in good yield (65-70%) and in high enantiomeric excess (>99%).
