Enzymatic procedures for the synthesis of water-soluble retinol derivatives in organic media

Improving ascorbyl oleate synthesis catalyzed by Candida antarctica lipase B in ionic liquids and water activity control by salt hydrates

“…Lipophilization reactions including synthesis of ascorbyl esters were recently reviewed by Villeneuve [9] and can be used in reactions with, e.g. vitamin A [10,11], B 6 [12] or flavonoids [13][14][15][16].…”

Synergism of Microwaves and Immobilized Enzyme Catalysis in Synthesis of Adipic Acid Esters in Nonaqueous Media

“…[1] Monoesters of adipic acid are particularly used in Kolbe's synthesis [2,3] and in regioselective transformations, and also as synthons for chiral building block, [4] whereas diesters are extensively used as precursors in the synthesis of biodegradable polymers and as lubricants. [10,11] Mostly all above-mentioned reactions have been carried out using reactors accompanied with traditional heat-transfer equipment. The reaction temperature for adipic acid esters is usually in the range of 100 to 1808C.…”

Aplicações sintéticas de lipases imobilizadas em polímeros

“…A atividade catalítica da lipase de Rhizomucor miehei em diferentes solventes orgânicos foi muito pequena para valores fixos de a w 44 . O efeito da atividade da água em reações biocatalisadas por lipases tem sido mostrado em vários trabalhos [45][46][47][48][49][50][51][52] .…”

“…Costa et al 60 discutiram os principais aspectos relacionados com a influência do solvente sobre a enantiosseletividade de hidrolases, principalmente as lipases. O efeito do solvente nas reações biocatalisadas também foi mostrado por outros autores 48,50,[61][62][63] .…”
