Enzymatic kinetic resolution of organochalcogenides in supercritical CO(2)

GARIANI, Rogerio A.; LUENGO, Fernando A. G.; VALE, Luiz A. S.; BAZITO, Reinaldo C.; COMASSETO, Joao V. (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

Enzymatic Kinetic Resolution of tert-Butyl 2-(1-Hydroxyethyl)phenylcarbamate, A Key Intermediate to Chiral Organoselenanes and Organotelluranes

PIOVAN, Leandro; PASQUINI, Monica D.; ANDRADE, Leandro H. (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 ...

Enzymatic kinetic resolution of racemic ibuprofen: past, present and future

José, Carla; Toledo, Victoria; Briand, Laura Estefania (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 ...

Multivariate curve resolution applied to kinetic-spectroscopic data matrices: Dye determination in foods by means of enzymatic oxidation

Boeris, Valeria; Arancibia, Juan Alberto; Olivieri, Alejandro Cesar (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 ...

Kinetic resolution of a drug precursor by Burkholderia cepacia lipase immobilized by different methodologies on superparamagnetic nanoparticles

ANDRADE, Leandro H.; REBELO, Lya P.; NETTO, Caterina G. C. M.; TOMA, Henrique E. (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 ...

Exploiting the enzymatic machinery of Arthrobacter atrocyaneus for oxidative kinetic resolution of secondary alcohols

Silva, Camila R.; Souza, Juliana Cedro; Araujo, Lidiane S.; Kagohara, Edna; Garcia, Thais P.; Pellizari, Vivian Helena; Andrade, Leandro H. (ELSEVIER SCIENCE BVAMSTERDAM, 2012)

We evaluated Arthrobacter atrocyaneus (R1AF57) as producer of oxidoreductases for oxidative kinetic resolution of racemic secondary alcohols via oxidation reaction. This bacterium was isolated from Amazon soil samples using ...

Tuning Lipase-catalysed Kinetic Resolution Of 2-substituted Thiophenes And Furans: A Scalable Chemoenzymatic Route To Masked γ-bis-oxo-alcohols
