New, easily removable poly(ethylene glycol) supports for the liquid-phase method of peptide synthesis

Molecular Recognition: Preparation of Polyrotaxan and Tubular Polymer from Cyclodextrin

“…PEG-bisamine (PEGBA), which is PEG with amino groups in both ends, was prepared from PEG-1450 according to the method described by Pillai et al [14].…”

Synthesis and characterization of poly(ethylene glycol) derivatives

“…In our route, derivative la was obtained with very little chain degradation by sodium hydride generation of PEG-alkoxide and subsequent reaction with p-toluene sulfonyl chloride, eq. (2)'": PEG-CH20H 2 PEG-CH20-Na+ PEG-CH20Ts (2) Unlike the tosylate, which is prone to decomposition upon extended storage, the mesylate [eq. were found to be stable upon storage.…”

Folate-conjugated methoxy poly (ethylene glycol)/poly (L-Alanine) amphiphilic block copolymeric micelles for targeted delivery of paclitaxel

“…First, Aminomonomethoxy poly (ethy1ene glycol)(MPEG-NH 2 ) was synthesized based on the principle of Gabriel synthesis. The detailed reaction and purification conditions could be found in Pillia's manuscript (PILLAI et al, 1980). Then, L-alanine-N-carboxvanhvdride(L-Alanine-NCA) was prepared by the following method: L-Alanine(5g) was put into a three-neck flask and dissolved in tetrahydrofuran (50ml).…”
