Biocatalytic resolution of saphenic acid. Substrate preferences for lipases A and B from Candida antarctica
Tjosås, Freddy; Anthonsen, Thorleif; Jacobsen, Elisabeth Egholm (Journal article; Peer reviewed, 2008) -
Immobilization does not influence the enantioselectivity of CAL-B catalyzed kinetic resolution of secondary alcohols
Jacobsen, Elisabeth Egholm; Andresen, Liv Siri; Anthonsen, Thorleif (Journal article; Peer reviewed, 2005)Decreasing enantioselectivity (E-value) by conversion has been observed in transesterification reactions of secondary alcohols catalyzed by a pure protein formulation of lipase B from Candida antarctica (Novozym 525 F). ... -
Lipase Catalysed Kinetic Resolution of Stiripentol
Jacobsen, Elisabeth Egholm; Anthonsen, Thorleif; El-Behairy, Mohammed Farrag; Sundby, Eirik; Aboul-Enein, Mohamed Nabil; Attia, Mohamed Ibrahim; El-Azzouny, Aida Abd El-Sattar; Amin, Kamilia M.; Abdel-Rehim, Mohamed (Journal article; Peer reviewed, 2012)Kinetic resolution of rac-Stiripentol, catalysed by lipase A from Candida antarctica by esterification with vinyl butanoate was performed with an E-value of 24. This allowed isolation of (3S)-Stiripentol with an ee of 86 ... -
Single Enantiomers from Racemates. Lipase catalysed Kinetic Resolution of Secondary Alcohols. In situ Stereoinversion
Jacobsen, Elisabeth Egholm; Anthonsen, Thorleif (Journal article; Peer reviewed, 2017)Kinetic resolution catalysed by lipases is a well suited strategy in order to provide enantiopure organic compounds. Factors affecting the enantiomeric ratio, the E-value, such as substrate structure, temperature effects, ... -
Synthesis and Fungicidal Activity of 2-Imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones and Their 5-Arylidene Derivatives
Liu, Hui-Ling; Li, Zongcheng; Anthonsen, Thorleif (Journal article; Peer reviewed, 2000)Five derivatives of 2-imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones and a series of their 5-arylidene derivatives have been synthesized and tested for antifungal activity against seven agricultural fungi. 2-Imino-3-( ...
