Activation of the C-F bond of benzylic fluorides was achieved using 1,1,1-tris(hydroxymethyl)propane (2) as a hydrogen bond-donating agent. Investigations demonstrated that hydrogen bond-donating solvents are promoting the activation and hydrogen bond-accepting ones are hindering it. However, the reaction is best

The interest in the applications of biocatalysis in organic syntheses has rapidly increased. In this context, lipases have recently become one of the most studied groups of enzymes. We have demonstrated that lipases can be used as biocatalyst in the

A synthetic route to prepare acetal-protected heterobifunctional poly(ethylene glycol), allyl(1-ethoxyethoxy)-PEG-OH (allyl(EE)-PEG-OH), was successfully established using a newly synthesized initiator, trimethylolpropane allyl (1-ethoxyethoxy) ether (TMPAEEE). Heterobifunctional allyl(OH)-mPEG and heterotrifunctional allyl(OH)-PEG-alkyne were obtained, respectively, after modification from this precursor polymer. The polymers
