Enzymatic Kinetic Resolution of tert-Butyl 2-(1-Hydroxyethyl)phenylcarbamate, A Key Intermediate to Chiral Organoselenanes and Organotelluranes
(MDPI AG, 2011)
The enzymatic kinetic resolution of tert-butyl 2-(1-hydroxyethyl) phenylcarbamate via lipase-catalyzed transesterification reaction was studied. We investigated several reaction conditions and the carbamate was resolved ...
Lipase-oxovanadium heterogeneous catalysis system: a robust protocol for the dynamic kinetic resolution of sec-alcohols
(2020-05-20)
Herein, we present a robust and eco-friendly dynamic kinetic resolution (DKR) protocol for secondary alcohols using a combined heterogeneous catalytic CAL−B/VOSO4 system at 50 °C in the relatively green solvent heptane. ...
Enzymatic kinetic resolution of racemic ibuprofen: past, present and future
(Taylor & Francis, 2015-06-30)
This review is a journey concerning the investigations of the kinetic resolution of racemic ibuprofen for the last 20 years. The relevancy of the pharmacological uses of the S( + ) enantiomer along with its higher cost ...
Kinetic resolution of a drug precursor by Burkholderia cepacia lipase immobilized by different methodologies on superparamagnetic nanoparticles
(ELSEVIER SCIENCE BV, 2010)
Burkholderia cepacia lipase was immobilized on superparamagnetic nanoparticles using three different methodologies (adsorption, chemisorption with carboxibenzaldehyde and chemisorption with glutaraldehyde) and employed in ...
Enzymatic kinetic resolution of organochalcogenides in supercritical CO(2)
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)

Relevance and bio-catalytic strategies for the kinetic resolution of ketoprofen towards dexketoprofen
(Taylor & Francis, 2017-11-10)
This review presents the most relevant investigations concerning the biocatalytic kinetic resolution of racemic ketoprofen to dexketoprofen for the last 22 years. The advantages related to the administration of the ...
Multivariate curve resolution applied to kinetic-spectroscopic data matrices: Dye determination in foods by means of enzymatic oxidation
(Elsevier Science, 2017-07)
In this work, the combination of chemometric techniques with kinetic-spectroscopic data allowed quantifying two dyes (tartrazine and carminic acid) in complex matrices as mustard, ketchup, asparagus soup powder, pumpkin ...
Formic Acid Electrooxidation on Platinum, Resolution of the Kinetic Mechanism in Steady State and Evaluation of the Kinetic Constants
(Wiley Blackwell Publishing, Inc, 2018-09)
A kinetic mechanism recently proposed for the formic acid oxidation (FAO) on platinum in acid solutions was analytically solved in order to verify its capability to correlate experimental measurements in steady state ...
Lipase-Catalyzed Kinetic Resolution of (+/-)-Mandelonitrile under Conventional Condition and Microwave Irradiation
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
The kinetic resolution of (+/-)-mandelonitrile was carried out using lipase from Candida antarctica under conventional condition (orbital shaker) and microwave irradiation in toluene, producing the (S)-mandelonitrile acetate ...
