P450BM3-Catalyzed Oxidations Employing Dual Functional Small Molecules [PDF]

, 2019
A set of dual functional small molecules (DFSMs) containing different amino acids has been synthesized and employed together with three different variants of the cytochrome P450 monooxygenase P450BM3 from Bacillus megaterium in H2O2-dependent oxidation

The shape of water in zeolites and its impact on epoxidation catalysis

Nature Catalysis, 2020
Solvent structures that surround active sites reorganize during catalysis and influence the stability of surface intermediates. Within zeolite pores, H2O molecules form hydrogen-bonded structures that differ substantially from bulk H2O.

Chemo-enzymatic epoxidation of fatty compounds – Focus on processes involving a lipase-catalyzed perhydrolysis step

Oléagineux, Corps gras, Lipides, 2008
At the industrial scale, the chemical Prileshajev reaction is currently the only method applied to produce epoxidized plant oils. Using enzymes could be an alternative way allowing an environmentally benign and more selective epoxidation reaction.

Kinetics of the Epoxidation of Geraniol and Model Systems by Dimethyldioxirane

Molecules, 2004
The mono-epoxidation of geraniol by dimethyldioxirane was carried out invarious solvents. In all cases, the product ratios for the 2,3 and 6,7 mono-epoxides werein agreement with literature values.
