2-Ethyl-2-oxazoline (EtOx) and methyl tosylate (MeOTs) were purchased
from Sigma-Aldrich (Vienna, Austria), purified by distillation over sodium
sulfate and stored in inert atmosphere. 2,2′-(Ethylenedioxy)diethanethiol
(DEG), dichloromethane, ethanol and deuterated chloroform were acquired from
Sigma-Aldrich (Vienna, Austria) and used without purification. Glycol
dimercaptoacetate (GDMA) was kindly provided by Bruno Brock (Marschacht,
Germany) and used without any further purification. The photoinitiator Lucirin
TPO-L®, ethyl-2,4,6-trimethylbenzoylphenylphosphinate, was
purchased from abcr GmbH (Karlsruhe, Germany). Deionized water was produced
through reverse osmosis. 2-But-3′-enyl-2-oxazoline (Bu⁼Ox),
2-nonyl-2-oxazoline (NonOx) and 2-dec-9′-enyl-2-oxazoline (Dc⁼Ox)
were synthesized according to literature protocols [22 –24 (link)],
purified by distillation and flash chromatography using chloroform as an eluent.
For the degradation studies, the enzymes (namely porcine liver esterase and
rabbit liver esterase), Eosin B, and the buffer solutions (pH = 4, 6, 8, and 10)
were acquired from Sigma-Aldrich (Vienna, Austria) and used as received.
