The enantioselective esterification of (R,S)-ibuprofen has been performed with Novozym 435TM in solvent media under reduced pressure. The nature of the solvent affects the activity and enantioselectivity of the lipase. High esterification rates are o

The reaction for the resolution of (R,S)-ibuprofen was scaled-up to yield gram quantities of (S)-ibuprofen. This was accomplished through two enantioselective reactions each catalysed by Novozym 435. In the first reaction, starting from 300 g of race

Two approaches have been used to monitor the enantioselective esterification of (R,S)-ibuprofen with 1-dodecanol catalyzed by Novozym 435. The first approach involves the use of a chiral column (Chiralcel OD) connected to a UV detector. The second ap

Water-soluble 2-hydroxypropyl-beta-cyclodextrin (Hp-beta-CyD), a cyclic and nonreducing oligosaccharide was used to enclose a hydrophobic guest molecule 1,1'-dimethylferrocene (DMF) to form a water-soluble yellow complex. At high concentrations (300

The lipase fromCandida rugosa has been shown to discriminate against erucic acid. Advantage of this property has been taken to produce trierucin from high-erucic acid rapeseed (HEAR) oil. A method has been developed for extracting erucic acid from th

The kinetics of the synthesis of triolein catalyzed by immobilized Mucor miehei lipase were studied. Equilibrium constants for the synthesis of mono-, di-, and triolein were calculated from the equilibrium compositions for different initial ratios of
