laccase from Trametes versicolor, and
2-ethyl hexyl bromide (95%)
were obtained from Sigma-Aldrich. para-Toluene sulfonic
acid (PTSA, 99%) was purchased from TCI. Silica gel (pore size 60
Å, 230–400 mesh particle size, particle size 40–63
μm) was obtained from Honeywell Fluka. All products and solvents
(reagent grade) were used as received except otherwise mentioned.
The solvents were of reagent grade quality and purified wherever necessary
according to the methods reported in the literature. Flash chromatography
was performed on a Grace Reveleris apparatus, employing silica cartridges
from Grace. Cyclohexane: ethyl acetate gradients were used as eluents.
The detection was performed through ELSD and UV detectors at 254 and
280 nm. The reactions under microwave irradiation were performed on
a Discover-SP from CEM, with the temperature measured by infrared;
the power of the apparatus is constantly adjusted to reach and then
stay at the set temperature.
