179249-15-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 179249-15-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,2,4 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 179249-15:
(8*1)+(7*7)+(6*9)+(5*2)+(4*4)+(3*9)+(2*1)+(1*5)=171
171 % 10 = 1
So 179249-15-1 is a valid CAS Registry Number.

Laccase-mediated Oxidations of Propargylic Alcohols. Application in the Deracemization of 1-arylprop-2-yn-1-ols in Combination with Alcohol Dehydrogenases

González-Granda, Sergio,Méndez-Sánchez, Daniel,Lavandera, Iván,Gotor-Fernández, Vicente

, p. 520 - 527 (2019/11/16)

The catalytic system composed by the laccase from Trametes versicolor and the oxy-radical TEMPO has been successfully applied in the sustainable oxidation of fourteen propargylic alcohols. The corresponding propargylic ketones were obtained in most cases in quantitative conversions (87–>99 % yield), demonstrating the efficiency of the chemoenzymatic methodology in comparison with traditional chemical oxidants, which usually lead to problems associated with the formation of by-products. Also, the stereoselective reduction of propargylic ketones was studied using alcohol dehydrogenases such as the one from Ralstonia species overexpressed in E. coli or the commercially available evo-1.1.200, allowing the access to both alcohol enantiomers mostly with complete conversions and variable selectivities depending on the aromatic pattern substitution (97–>99 % ee). To demonstrate the compatibility of the laccase-mediated oxidation and the alcohol dehydrogenase-catalyzed bioreduction, a deracemization strategy starting from the racemic compounds was developed through a sequential one-pot two-step process, obtaining a selection of (S)- or (R)-1-arylprop-2-yn-1-ols with excellent yields (>98 %) and selectivities (>98 % ee) depending on the alcohol dehydrogenase employed.

Aryl propargylic alcohols of high enantiomeric purity via lipase catalyzed resolutions

Waldinger, Claudia,Schneider, Manfred,Botta, Maurizio,Corelli, Federico,Summa, Vincenzo

, p. 1485 - 1488 (2007/10/03)

A variety of substituted aryl propargylic alcohols were prepared via lipase catalyzed resolutions, the enantioselective hydrolysis of the corresponding esters being the method of choice.
